PhD project: Flavour Physics with LHCb

Project description

The LHCb experiment at the LHC is designed to perform tests of the flavour sector of Standard Model with unprecedented precision. These measurements constrain fundamental parameters of the CKM matrix of the Standard Model and are sensitive to the virtual effects of new physics through loop-induced contributions. The experiment has already collected the largest samples of bottom and charm quarks ever collected. This sample, together with a state of the art detector, provides a wide range of opportunities for physics studies. During the current LHC run the dataset will more than double in size. In the 2019 shutdown LHCb will be upgraded to allow running at higher luminosity with 40 MHz readout to allow to collect even larger datasets.

The main focus of the group is the precision determination of the Bs mixing parameters, in particular the Bs mixing phase φusing the decays Bs → J/ψ φ and Bs → φ φ and we lead LHCbs efforts in this area.The group is also involved in a range of studies of both charmless b-decays and b-decays to final states containing charmonia. These exploit the large collected dataset to make precision determination of B hadron parameters such as lifetimes and masses and to study exotic charmonia states such as the X(3872) and the recently discovered pentaquark candidates.

The group is responsible for monitoring and maintaining the performance of the photodetectors of the current RICH system and is responsible for Quality Assurance and commissioning of the new MaPMT photodetectors that will be installed for the upgrade. We also has an interest in exploiting GPUs for trigger and offline applications with the upgraded detector.

Our PhD projects allow students to play a major role in studies in all of these areas, several of which have the potential to reveal physics beyond the Standard Model.
