Abstract

The LHCb experiment is dedicated to the study of heavy flavour physics at the LHC machine. Its primary motivation is to study with high statistics and precision CP violation and rare B hadron decays, to improve the knowledge of the Standard Model or to get indirect hints of new physics contribution to the flavour physics. The main experimental features of the experiment are presented and the sensitivities on some important measurement that LHCb will perform since the first data will be available are discussed.

Highlights

  • In the last decade the experiments at the Bfactories and at Tevatron contributed to an impressive improvement in the understanding of the Standard Model (SM)

  • If New Physics (NP) exists at a not too high energy scale (∼ TeV), it could manifest itself indirectly in beauty or charm meson decays that proceed through loop diagrams, where virtual NP particles could contribute in addition to the SM ones

  • Since these processes are usually suppressed in the SM, the eventual NP contributions should be easier to be measured

Summary

Introduction

In the last decade the experiments at the Bfactories and at Tevatron contributed to an impressive improvement in the understanding of the Standard Model (SM). Thanks to the high efficiency of the HLT di-muon trigger on this channel and the excellent tracking and particle identification performance, LHCb will collect about 113 events in 2 fb−1 of integrated luminosity [7]. At present the experimental situation is limited by the low statistics (O(100) events) at the B-factories [8] To study this channel efficiently LHCb will use a dedicated HLT exclusive selection. With a full three-angular analysis of the final state distributions the expected precision on φs is 0.023 rad In addition to this channel φs can be measured in many different CP-eigenstate modes, that in general have smaller statistics and higher background, providing a lower sensitivity to φs. If the present Tevatron results will be confirmed, LHCb will be able to measure it with a > 3σ sensitivity
