The physics performance of LHCb

The LHCb experiment is based on a single arm forward spectrometer optimized to study CP violation in the B system at the LHC. The experiment includes a dedicated trigger system, particle identification and a precise vertex determination; recent developments in these areas will be summarized. The detector will provide precise measurements of all angles of the unitarity triangle, the length of one of the sides (via Bs0−B̄s0 mixing) and the height of the triangle. The physics performance for selected channels will be reviewed.
