Radiative decays at LHCb

详细

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, B⁰ → K^*0γ and B_s → ϕγ, the direct CP asymmetry in B⁰ → K^*0γ decay channel and the observation of the photon polarization in the B^± → K^±π^∓π^±γ 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.
