Studies of Hadronic B Decays at LHCb

Hadronic B decays are important decays for CP-violation studies and to search for beyond the Standard Model (SM) effects. CP-violation results obtained from the decays B→DK where D represents D0 or D¯0 and from the decays B→hh where h denotes K or π are presented. The B→DK decay modes are due to tree level diagrams while the B→hh are sensitive to loop diagrams and thus to New Physics. Results from a full angular analysis of the BS0→ϕϕ decay modes are also presented as well as the effective lifetime measurement using the BS0→KK mode. The analyses presented here are based on 1.0 fb−-1pp collision data collected in 2011 with the LHCb detector.
