We are responsible for the EvtGen Monte Carlo generator within the experiment.
Trigger and data stripping
We are involved with the HLT2 (high-level trigger) and data stripping activity.
We are interested in the physics potential of an LHCb upgrade. In particular, we are examining the requirements that operating at much higher rates will impose on the vertex detector. We are involved in the upgrade of the VELO subdetector.
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.
