Direct CP Violation in Charmless B Decays at LHCb

By Jussara M. de Miranda

Abstract

Using data collected by LHCb experiment in 2011 we report the measurements of charge asymmetries in charmless decays of B mesons in two or three charged kaons or pions. We find positive charge asymmetries in the channels Bs->K-pi+(3.3 sigmas), B+->K+pi+pi- (2.8 sigmas), and B+->pi+pi+pi- (4.2 sigmas) and negative in B0->K+pi-(6 sigmas),B+->K+K+K- (3.7 sigma), B+->K+K-pi+ (3.0 sigma).Comment: Proceedings of CKM 2012, the 7th International Workshop on the CKM Unitarity Triangle, University of Cincinnati, USA, 28 September - 2 October 201
