We are members of the VErtex LOcator subdetector group and authors of the VELO performance paper (arXiv:1405.7808). We are involved in the upgrade of the VELO subdetector, and planning for future upgrades to cope with ever higher data rates.
We are responsible for the EvtGen Monte Carlo generator within the experiment.
Trigger, data stripping and real time analysis
We are members of the TORCH collaboration, carrying out R&D for a novel time-of-flight detector that could provide particle identification information, to discriminate between charged pions, kaons and protons at low momentum.
Physics Analysis (more information here)
We have leading roles in the collaboration in measurements related to the angle γ (gamma) of the so-called Unitarity Triangle and of rare b hadron decays mediated by the b→sμ+μ− transition. We also have interests in several other areas, particularly in analyses involving Dalitz plot analysis. We hosted an LHCb UK workshop on Dalitz plot analysis in October 2009.
