LHCb : measurement of CP violation in B decays: Conference MT17

The aim of the LHCb experiment is to fully investigate CP violation in the B d and B s systems, and to possibly reveal new physics beyond the Standard model. The key detector requirements are: - efficient trigger for many B-decay topologies - excellent particle identification for pi -K separation in a wide momentum range - good decay-time resolution in particular to resolve fast B s oscillations - good mass resolution to efficiently suppress background European Organization for Nuclear Research
