SUMMARY:Particles in Space: Sciences and Instruments
DESCRIPTION:Space Astroparticle Physics has been making rapid progress in 
 recent years. Advanced particle detection technologies developed for accel
 erator experiments have been successfully applied to instruments deployed 
 in space. Unprecedented measurement precisions have been achieved\, and th
 e frontier of direct cosmic ray detection has been pushed to the 100 TeV\,
  and soon to the PeV\, region. In addition\, cutting-edge particle detecti
 on technologies are being applied to innovative energetic particle\, x-ray
  and gamma-ray space instruments. In this talk I will use several current 
 and future projects as examples to illustrate the science impact and instr
 ument advancement of this growing research field.\n\nSpeaker:\n* Prof Xin

SUMMARY:Higgs Boson Properties as a Window to New Physics
DESCRIPTION:So far\, direct searches at the LHC have not observed any hint
 s for physics beyond the Standard Model. New physics outside the reach of 
 direct searches can affect the properties of Standard Model particles at L
 HC energies. These deviations can be described using general approaches li
 ke effective field theories.  \n\nOne of the most promising particles to 
 look for these deviations is the Higgs boson. Additional couplings can aff
 ect kinematic distributions\, like the transverse momentum of the Higgs bo
 son or the angular difference of the two leading jets\, testing properties
  like its CP symmetry. In my presentation I will discuss different measure
 ment approaches like differential and simplified template cross sections f
 ocussing on recent results from the ATLAS experiment in the di-tau final s
 tate and for comparison in the di-photon final state. The aim of these mea
 surements is to maximise our knowledge about the Higgs boson with the curr
 ently available dataset and make interpretations in effective field theori
 es and specific extensions of the Standard Model possible. \n\nSpeaker:\n

SUMMARY:Recents results on sterile neutrino searches in MicroBooNE
DESCRIPTION:The MicroBooNE experiment utilizes a liquid argon time project
 ion chamber to detect neutrinos emanating from Fermilab's Booster Neutrino
  Beam (BNB) and the Neutrinos at the Main Injector (NuMI) beam. MicroBooNE
  is investigating the observed low-energy excess (LEE) of electron neutrin
 o and antineutrino charged current quasielastic events reported by the Min
 iBooNE experiment. The MiniBooNE anomaly has garnered significant attentio
 n over the past 20 years including previous MicroBooNE investigations into
  both anomalous electron and photon excesses\, but its origin remains uncl
 ear. This presentation will report on three different searches that try to
  explain the MiniBooNE anomaly: an electron neutrino excess utilizing the 
 full 5-year dataset\, three new and improved searches for single photons (
 NC Delta radiative single photon production\, first search for neutrino-in
 duced coherent single photon production and an inclusive search for single
  photons)\, and the first direct test of dark sector models in which dark 
 neutrinos decay into missing energy and visible e⁺e⁻ pairs. Additional
 ly\, we present the status of searches for short baseline neutrino oscilla
 tions within the framework of a 3+1 eV-scale sterile neutrino model. This 
 work combines data from both the BNB and NuMI beams leveraging their subst
 antially different ratios to mitigate degeneracy resulting from the cancel
 lation of appearance and disappearance allowing the enhancement the experi
 ment's sensitivity.\n\nSpeaker:\n* Dr Miquel Nebot-Guinot (School of Physi

SUMMARY:Building the case for a Muon Collider
DESCRIPTION:The Large Hadron Collider (LHC) has enjoyed great success in c
 ompleting the last piece of the Standard Model (SM): Electroweak Symmetry 
 Breaking characterized by a single Higgs boson. The discovery of the Higgs
  boson by the ATLAS and CMS experiments made the SM self-consistent. Howev
 er experimental observations tell us that the model is not complete (no gr
 avity\, neutrino masses or Dark Matter). This is a clear indication of phy
 sics Beyond the Standard Model (BSM). Current experiments have so far fail
 ed to provide an answer to any of these questions. While the LHC run is fa
 r from over\, such large scale facilities have a very long lead times (dec
 ades). It means we need to start planning for them now.\n\nThe Muon Collid
 er provides an excellent environment for studying the stated goals of a fu
 ture collider. The fully leptonic initial state allows for precision measu
 rements of the Standard Model and can probe much higher energies with a sm
 all ring size. However the instability of the muons create challenges for 
 both the accelerator and detectors. The seminar will give an overview of t
 he significant progress that has happened on both fronts and highlight the
  areas that still needed Research and Development.\n\nSpeaker:\n* Dr. Karo

SUMMARY:Searching for light-dark matter with Spherical Proportional Counte
 rs
DESCRIPTION:The precise particle nature of dark matter\, which makes up mo
 st of the matter in the universe\, remains elusive and is one of the leadi
 ng open questions in physics. The NEWS-G collaboration is searching for li
 ght dark matter candidates with a novel gaseous detector concept\, the sph
 erical proportional counter. Access to the mass range from 0.05 to 10 GeV 
 is enabled by the combination of low energy threshold\, light gaseous targ
 ets (H\, He\, Ne)\, and highly radio-pure detector construction. Initial N
 EWS-G results obtained with SEDINE\, a 60 cm in diameter spherical proport
 ional counter operating at LSM (France)\, excluded for the first time WIMP
 -like dark matter candidates down to masses of 0.5 GeV. The collaboration 
 currently operates a 140 cm in diameter spherical proportional counter\, S
 NOGLOBE\, constructed at LSM using 4N copper with 500 um electroplated inn
 er layer\, which is currently collecting data in SNOLAB (Canada). This se
 minar will discuss recent NEWS-G results and the developments in spherica
 l proportional counter instrumentation and detector understanding that con
 tributed to the first results with SNOGLOBE from its commissioning data. T
 he next stage of the experiment\, using detectors constructed from ultra-p
 ure electroformed copper directly in the underground laboratory where they
  will be operated will be presented\, with the construction of a 30 cm in 
 diameter detector commencing this year in the Boulby underground laborator
 y\, and the plans to construct a larger scale detector\, DarkSPHERE - with
  both detectors having the potential to break new ground in the dark matte
 r puzzle. \n\nSpeaker:\n* Dr. Patrick Knights (University of Birmingham)

SUMMARY:Silicon Detector Upgrades in ALICE
DESCRIPTION:The ALICE experiment at LHC explores the properties of strongl
 y interacting matter at extreme energy densities\, where quarks and gluons
  are expected to form a quark-gluon plasma. A core component of ALICE is i
 ts Inner Tracking System (ITS)\, a silicon-based detector optimized for hi
 gh-precision tracking and vertexing. This seminar will provide an overview
  of the progressive upgrades of the ITS\, starting with ITS2\, which intro
 duced monolithic active pixel sensors (MAPS) to significantly enhance poin
 ting resolution and tracking efficiency. Operational experience from the e
 arly years of Run 3 will be reviewed\, with a focus on key lessons learned
  and their relevance for the development of future tracking systems. The c
 urrent R&D status of ITS3 will also be presented\, highlighting the develo
 pment of curved wafer-scale MAPS sensors designed in 65 nm CMOS technology
 . This innovative approach aims to reduce the material budget and enhance
  tracking precision near the interaction point. The seminar will conclude 
 with an overview of the ALICE 3 concept\, which focuses on next-generation
  silicon detector developments designed to enable advanced studies of the
  quark-gluon plasma while supporting novel investigations in broader areas
  of QCD and fundamental physics.\n\nSpeaker:\n* Dr Jian Liu (University of

SUMMARY:R2D2 project for the future of double beta decay
DESCRIPTION:To search for $\\beta\\beta0\\nu$ decay with unprecedented sen
 sitivity\, the R2D2 collaboration is developing a radial time projection c
 hamber with a fiducial mass of half a tonne of $^{136}$Xe at high pressure
  able to identify the two emitted electrons. The various approaches implem
 ented to eliminate the radioactive background are presented in terms of de
 tector design\, topological recognition of interactions\, and event energy
  reconstruction. The developed tools allow for the disentangling of the so
 ught-after signal from the background\, and the projected sensitivity afte
 r ten years of data taking yields a half-life limit exceeding $10^{27}$ ye
 ars\, along with a constraint on the effective neutrino mass $m_{\\beta\\b
 eta}$. With larger mass of $^{136}$Xe\, The detector could exclude the inv
 erted neutrino mass hierarchy region\, depending on the final experimental
  background.\n\nSpeaker:\n* Dr. Fabrice Piquemal (Laboratoire de Physique

SUMMARY:On the hunt for lepton number violation: the latest from the NEXT 
 0vBB experiment 
DESCRIPTION:Neutrinos are one of the least understood particles in the Sta
 ndard Model (SM) and may be one of the keys needed to answer important que
 stions such as the origin of the matter-antimatter asymmetry and whether l
 epton number is violated. They have already contributed to beyond the SM e
 ffects such as neutrino oscillations and further questions such as what is
  the neutrino mass\, why are they so light\, do neutrinos violate the CP s
 ymmetry\, and whether they are their own antiparticle (Majorana) remain. T
 he observation of a rare decay process known as neutrinoless double beta d
 ecay (0vBB) is the most feasible way to determine the nature of the neutri
 no and is currently an active field of research. The NEXT experiment aims 
 to search for 0vBB using the xenon-136 isotope with a high-pressure gaseou
 s time projection chamber (TPC). NEXT-100 is the latest experiment in this
  program and is currently taking physics data in the Canfranc Underground 
 Laboratory in Spain. In this talk\, I will give an overview of neutrinoles
 s double beta decay\, an update on the current status of the NEXT-100 expe
 riment\, and my research program on NEXT which includes the successful ins
 tallation of the NEXT-100 electroluminescence region\, new topological ana
 lyses\, probing 0vBB decay mechanisms\, and gaseous xenon TPC simulations.

SUMMARY:Extending the LHC reach to very long lifetimes: the design concept
  and current status of the ANUBIS experiment
DESCRIPTION:Many beyond-the-standard model theories propose the existence 
 of new 'long-lived' particles (LLPs) with macroscopic decay lengths that m
 ay be produced in high energy collisions at the LHC. While extensive searc
 hes for LLPs have been performed by existing LHC experiments such as ATLAS
 \, CMS\, and LHCb\, their sensitivity to very long-lived models (ct>~10 m)
  is constrained by the physical size of the detectors. The proposed ANUBIS
  experiment is designed to significantly extend experimental sensitivity t
 o these very long-lived models by instrumenting the ceiling of the ATLAS d
 etector cavern with RPC detectors. In addition to extending the decay volu
 me\, the transverse positioning provides sensitivity to LLP models with hi
 gh-mass mediators\, complementing the sensitivity of existing forward dete
 ctors to lower-mass models. In this talk\, the physics case for ANUBIS pro
 posal will be presented alongside its expected backgrounds\, projected phy
 sics reach for several benchmark LLP models\, and the current status and l
 atest results from the proANUBIS demonstrator within the ATLAS cavern.\n\n

SUMMARY:Topponium: the new physics we nearly missed!
DESCRIPTION:The greatest success of the LHC has been to dispel the myth th
 at hadron colliders are not precision physics machines. From the discovery
  of the Higgs boson\, the measurement of the W boson mass\, the discovery 
 of dozens of new bound states\, and now the observation of subtle and elus
 ive QCD pseudo-bound state of topponium\, the LHC has probed the SM to unp
 recedented precision. In this seminar I will give an overview of the histo
 ry of precision top properties measurements at the LHC and how they lead t
 o the discovery of a new pseudo-bound state at the very threshold of ttbar
  production by the ATLAS and CMS experiments. I will also use this discove
 ry as both an example and a caution about the limitations in current exper
 imental particle physics techniques and highlight the steps that must be t
 aken to exploit the forthcoming HL-LHC to it’s full potential if we are 
 to have a chance to discover physics beyond the Standard Model.\n\nSpeaker

SUMMARY:Towards the discovery of neutrinoless double beta decay : first re
 sults from LEGEND
DESCRIPTION:The sheer abundance of neutrinos all around us makes it hard t
 o believe that we still don’t understand so much about them. It is this 
 allusiveness that makes research into neutrino physics so fascinating\, an
 d within this unknown\, many mysteries about the universe could be unfolde
 d.\n \n A discovery of the hypothetical neutrinoless double beta decay (0$
 \\nu\\beta\\beta$) process would have profound implications. It would prov
 e that lepton number is not a conserved quantity\, prove that neutrinos ar
 e Majorana in nature\, and constrain the mass hierarchy.\n \n The LEGEND e
 xperiment is designed to search for 0$\\nu\\beta\\beta$ using Ge-76 enrich
 ed high purity germanium detectors that are immersed in liquid argon. LEGE
 ND-200 (L200)\, operating at LNGS in Italy\, builds on the successes in ba
 ckground suppression and analysis techniques from the Majorana Demonstrato
 r and GERDA experiments. L200’s first results are based on 61 kgyr of ex
 posure with an estimated background index of $0.5^{+0.3}_{-0.2}$ cts/(keV 
 ton yr). Data from GERDA and the Majorana Demonstrator were combined with 
 L200’s for a joint analysis\, yielding a 90% CL sensitivity of $2.8\\tim
 es10^{26}$ yr and setting a new lower limit of > $1.9\\times10^{26}$ yr\, 
 for the half-life of 0$\\nu\\beta\\beta$. Assuming the decay mechanism is 
 mediated by the exchange of a light Majorana neutrino\, this half-life lim
 it corresponds to an upper limit on the effective Majorana mass of $m_{\\b
 eta\\beta}$ < 75-200 meV. In an attempt to encourage our nuclear theory co
 lleagues\, an additional limit has been set\, with $m_{\\beta\\beta}$< 320
  meV\, utilising the recent developments in uncertainty-quantified nuclear
  matrix elements.\n \n In this talk\, I will present L200’s first result
 s published in the recently released paper (https://arxiv.org/pdf/2505.104
 40) with some added detail about the detector technology. I will also brie
 fly showcase the outlook for the next phase of the LEGEND experiment\, L10
 00\, with some context for the UK double beta decay community.\n\nSpeaker:

SUMMARY:The land of dark matter: a collider perspective
DESCRIPTION:Dark Matter (DM) constitutes a substantial but unexplained fra
 ction of the universe\, and the Standard Model (SM) of particle physics of
 fers no viable candidate\, highlighting the need for new theories and dete
 ction strategies. Numerous theoretical models predict DM particles\, makin
 g their detection a strong pillar of the Large Hadron Collider (LHC) physi
 cs program. Yet\, no direct evidence has been found so far. The lack of di
 scovery indicates that if DM lies within the LHC’s reach\, its experimen
 tal signature may be subtle. New theories suggest DM isn’t just one part
 icle\, but part of a hidden dark sector (DS). This DS is governed by a new
  dark force binding DM in a way that mirrors the SM\, described by the dar
 k Quantum Chromodynamics (dark QCD) framework. This dark force mediates in
 teractions within the DS and between DS and SM particles. Dark QCD models 
 predict fundamental components\, i.e. dark quarks\, confined at an energy 
 scale comparable to that of QCD\, which hadronise to form dark hadrons dec
 aying within the detector. Depending on their lifetimes\, these dark hadro
 ns can produce unique collider signatures like prompt semi-visible jets or
  displaced emerging jets. With new particle reconstruction techniques\, ex
 periments like ATLAS and CMS are finally starting to probe this hidden sec
 tor and the unconventional signatures that come along with it. Early exper
 imental results are emerging\, and we’re only at the beginning. In this 
 talk\, I’ll start with an overview of the ATLAS dark sector paradigm and
  then explore in detail what we’re searching for\, how we’re going aft
 er it\, and the kinds of unconventional signals that might appear in the d
 etector.\n\nSpeaker:\n* Dr. Sukanya Sinha (University of Manchester)

SUMMARY:Mirages\, Oases\, Mountains: a journey through the Standard Model
DESCRIPTION:Success has been hard on particle physics. In one century we h
 ave gone from learning that atoms consist of nucleons to a complete and se
 lf-consistent description of microscopic nature which is able to accuratel
 y predict the properties of fundamental particles to the twelfth decimal p
 lace. And yet this Standard Model\, which stretches out as far as the eye 
 can see in our laboratories\, is manifestly at odds with our best descript
 ions of the very macroscopic universe and its beginnings. Are we one ascen
 t away from seeing a new world\, or will we reach the top of the next ridg
 e merely to better appreciate the plateau of knowledge which has become ou
 r home? I will reflect on the decades-long experimental quest for a more c
 omplete theory beyond the Standard Model and the machines and tools which 
 are our essential companions on this journey.\n\nSpeaker:\n* Dr. Vava Glig

SUMMARY:Opportunities and challenges to study solar neutrinos with a Q-Pix
  pixel readout
DESCRIPTION:The study of solar neutrinos presents significant opportunitie
 s in astrophysics\, nuclear physics\, and particle physics. However\, the 
 low-energy nature of these neutrinos introduces considerable challenges to
  isolate them from background events\, requiring detectors with low-energy
  threshold\, high spatial and energy resolutions\, and low data rate. We p
 resent the study of solar neutrinos with a kiloton-scale liquid argon dete
 ctor located underground\, instrumented with a pixel readout using the Q-P
 ix technology. We explore the potential of using volume fiducialization\, 
 directional topological information\, light signal coincidence and pulse-s
 hape discrimination to enhance solar neutrino sensitivity. We find that di
 scriminating neutrino signals below 5 MeV is very difficult. However\, we 
 show that these methods are useful for the detection of solar neutrinos wh
 en external backgrounds are sufficiently understood and when the detector 
 is built using low-background techniques. When building a workable backgro
 und model for this study\, we identify γ background from the cavern walls
  and from capture of α particles in radon decay chains as both critical t
 o solar neutrino sensitivity and significantly underconstrained by existin
 g measurements. Finally\, we highlight that the main advantage of the use 
 of Q-Pix for solar neutrino studies lies in its ability to enable the cont
 inuous readout of all low-energy events with minimal data rates and manage
 able storage for further offline analyses.\n\nSpeaker:\n* Dr Miguel Ángel

SUMMARY:Investigating the Digital Preservation of Raw Bubble Chamber Data
DESCRIPTION:Many of the defining advances in particle physics during the m
 id twentieth century were made at bubble chamber experiments. The particle
  physics group of the University of Birmingham have a rich history of invo
 lvement in bubble chamber experiments dating back to the 1950s. As part of
  this legacy\, the group hold an extensive collection of photographic film
  recorded by experiments at the CERN 2m Hydrogen Bubble Chamber (HBC)\, wh
 ich operated between 1965 and 1976. These photographic records of particle
  interactions in the chamber volume represented the primary raw data forma
 t of such experiments\, from which particle trajectories and momenta were 
 then reconstructed from careful measurements of the film. Remarkably\, nea
 rly 60 years since the chamber was commissioned\, the basic technical info
 rmation required to reconstruct particle interactions from measurements of
  2m HBC film has been comprehensively preserved by CERN and is publicly av
 ailable. This talk will describe an effort to digitally preserve this data
 set\, towards the establishment of a unique educational resource and the p
 otential revival its scientific exploitation.\n\nSpeaker:\n* Dr. Andrew St

SUMMARY:LiquidO opaque scintillator detectors and their physics opportunit
 ies
DESCRIPTION:Radiation detectors enable many aspects of our modern lives\, 
 from the light sensors in our smartphone cameras to PET scanners that info
 rm treatment of cancer. Particle physicists have often led the development
  and exploitation of cutting edge radiation detectors to identify particle
 s while measuring their energies\, positions and directions. Many radiatio
 n detectors use scintillators\, which traditionally have nearly always bee
 n transparent to allow detection of the light. Our new counter-intuitive a
 pproach called “LiquidO” is to use highly scattering opaque scintillat
 or. The opacity causes the light to bounce around close to where it is pro
 duced and then optical fibres extract the light. By looking at which fibre
 s are hit and how much light each one sees\, precise particle position and
  directional information can be obtained. We've demonstrated that our appr
 oach outperforms existing scintillator technology by a factor of two. With
  further R&D the resolution is expected to improve by 5-10x\, for a simila
 r cost to existing technology. Or\, importantly for some applications\, re
 duce the detector cost by 5-10x while maintaining the resolution. There ar
 e multiple applications for high-resolution and cost-effective radiation i
 maging\, from Compton cameras for gamma ray imaging to precision muon tomo
 graphy. In particle physics\, the CLOUD neutrino experiment will pioneer n
 ew physics measurements using the novel LiquidO opaque scintillator techno
 logy.\n\nSpeaker:\n* Dr. Jeff Hartnell (University of Sussex)

SUMMARY:Trigger-Level Analysis at ATLAS
DESCRIPTION:The ATLAS Collaboration recently released its full Run-2 dijet
  Trigger-Level Analysis (TLA)\, which processes an unprecedented dataset o
 f more than 60 billion events within a single analysis. By reconstructing 
 jets directly in the high-level trigger\, TLA achieves a data-taking rate 
 more than twenty times higher than the nominal ATLAS readout. This approac
 h enables searches for new physics in dijet final states that would otherw
 ise be limited by data-acquisition bandwidth. While conventional LHC dijet
  searches are typically restricted to masses above 1 TeV\, the presented a
 nalysis extends the accessible mass range down to 375 GeV. As a result\, t
 he presented analysis sets world-leading exclusion limits for simplified d
 ark matter models.\n\nSpeaker:\n* Dr. Tobias Fitschen (University of Manch

SUMMARY:System testing for the ITk pixel detector
DESCRIPTION:In order to operate in the harsh radiation conditions of the H
 igh-Luminosity Large Hadron Collider (HL-LHC)\, the ATLAS experiment at CE
 RN will undergo a number of upgrades over the LHC Long Shutdown 3 (2026-20
 30). Notably\, the ATLAS Inner Detector will be completely replaced with a
 n all-silicon Inner Tracker (ITk)\,  designed to cope with increased occu
 pancy\, bandwidth\, and radiation damage. The ITk is comprised of a hybrid
  silicon pixel detector at its heart\, surrounded by a silicon strip detec
 tor.\n\nThe ITk Pixel system will cover an active area of approximately 13
  m2\, will have around 5 billion readout channels\, and will use innovativ
 e concepts such as serial powering and CO2 cooling to an unprecedented sca
 le. The design and prototyping period for the ITk Pixel detector is now co
 mplete\, with many detector components already in the production or pre-pr
 oduction phase. System-level tests play a crucial role in the ITk Pixel te
 sting programme\, allowing validation of the interfaces between different 
 detector components\, and preparation for detector commissioning and opera
 tion. An overview of recent system-test efforts will be presented\, includ
 ing the recent operation of a 14-module serial powering chain at CERN.\n\n

SUMMARY:Probing the Higgs potential and beyond with multi-Higgs production
  at LHC
DESCRIPTION:Higgs boson pair production has received much attention in rec
 ent years\, in part due to the ATLAS and CMS experiments achieving much gr
 eater sensitivity to this process than was initially expected. The theoret
 ical implications are broad\, ranging from probing the form of the Higgs p
 otential (with consequences for cosmology via the electroweak phase transi
 tion) to constraining theories beyond the Standard Model that predict new 
 particles that might decay into Higgs bosons or modify known interactions 
 in ways that can be described using effective field theories. More recentl
 y\, both experiments have additionally begun studying triple Higgs boson p
 roduction to set the first constraints on the Higgs quartic coupling and f
 urther explore the space of extended scalar sector models. This talk will 
 present a view of where the field currently stands on multi-Higgs physics
  (with a few highlights from the speaker's work with ATLAS) and where it i
 s going in the HL-LHC era and beyond.\n\nSpeaker:\n* Dr. William Balunas (
