Assuming that the corrections to relevant Wilson coefficients from new physics (NP) contain the possible CP phases, we analyze the constraints on the NP corrections from the updated experimental data on rare B decays from LHCb, BABAR, and BELLE, etc. systematically. Through global fit among the theoretical evaluations and corresponding experimental observations, we find that the possible CP phases of the corrections to relevant Wilson coefficients from NP affect the allowed parameter space obviously.

We present a review of the operation and of the most recent results from the LHCb experiment at the LHC collider, based on the analyses performed using the data collected in 2010 and 2011, which correspond to an integrated luminosity of ~ 1 fb-1. These measurements set stringent new limits on the contributions of New Physics processes in the field of rare b decays, and in the search for CP violation in B0 and [Formula: see text] mesons decays. In addition, a summary of results from studies of CP violation in the charm sector are presented, together with measurements in quarkonia production, in spectroscopy, in electroweak physics and in searches for exotica. The planned upgrade of LHCb is also briefly discussed.
