Abstract

The B c → B s π decay is studied with the perturbative QCD approach. Three types of wave functions for B s meson are considered. The transition form factor \(F_0^{B_c \to B_s } (0)\) and the branching ratio Br(B c →B s π) are sensitive to the model of the B s meson wave functions. With appropriate inputs, our estimate on Br(B c →B s π) is comparable with the recent LHCb measurement. A clear signal of B c → B s π decay should be easily observed at the Large Hadron Collider.
