Radiative Decays at LHCb

摘要

Precise measurements on rare radiative B decays are performed with the LHCb experiment at LHC. The LHCb results regarding the ratio of branching fractions for two radiative decays, B-0 -> K*(0)gamma and B-s -> phi gamma the direct CP asymmetry in B-0 -> K*(0)gamma decay channel and the observation of the photon polarization in the B-+/- -> K-+/-pi(+/-)pi(+/-)gamma decay, are included. The first two measurements were performed in 1 fb(-1) of pp collisions data and the third one in 3 fb(-1) of data, respectively.
