Studies of B-Hadron Decays to Charmless Final States at LHCb

Mostrar otras versiones (1)

LHCb has a rich programme studying hadronic B-decays and is already showing that with early data it can produce precision measurements which improve on current world averages. The preliminary results presented include the new world's best measurements of the Acp(Bd -> K+ pi-) = -0.088 +/- 0....

Sumario:LHCb has a rich programme studying hadronic B-decays and is already showing that with early data it can produce precision measurements which improve on current world averages. The preliminary results presented include the new world's best measurements of the Acp(Bd -> K+ pi-) = -0.088 +/- 0.011 (stat) +/- 0.008 (syst) and tau(Bs -> K+ K-) = 1.440 +/- 0.096 (stat) +/- 0.010 (syst) ps. These were obtained using the full 2010 data sample containing 37 pb-1 and also 320 pb-1 of the 2011 data. The first observation of CP violation in Bs -> pi+ K- is also presented.
