FASER: A small LHC experiment probing new physics in far corners

FASER is a small experiment at the LHC designed to search for new, light and extremely weakly-interacting particles at CERN's Large Hadron Collider (LHC), as well as measure the interactions of Standard Model neutrinos. The experiment targets physics produced in the very forward direction in LHC's high energy proton-proton collisions. The detector lies in wait 480 m downstream of the ATLAS interaction point, aligned with the beam collisions axis. FASER has been collecting data at the LHC since 2022, setting limits on long-lived particles such as Dark Photons and making first measurements of collider neutrino interactions. 

During the seminar, I will present the FASER detector and its latest physics results, as well as the physics potential of far forward experiments such as FASER at the HL-LHC.
