Abstract
During 2011 and 2012 the LHCb detector collected data coming from proton-proton collision corresponding to an integrated luminosity of 1 fb−1 at a center-of-mass energy of 7 TeV and 2 fb−1 at a center-of-mass energy of 8 TeV, respectively. Using this data sample LHCb can measure with an unprecedented precision the parameters associated to the CKM matrix. In the neutral B meson system, CP violation is induced from the interference of decay with or without mixing, with possible implications in the search for physics beyond the Standard Model. Recent results obtained by LHCb Collaboration are presented, which give access to the β and φs parameters, in particular the analysis of the decays B0 → J/ψK0s, B0s → J/ψK+K− and B0s → J/ψπ+π−. Finally the first LHCb measurements of CP violation in the channels B0 → D+D− and B0s → D+s K− are presented.
