Abstract：
The rare decay B⁺→D⁺_sK^*0 can occur only via annihilation diagrams in the Standard Model. We calculate the branching ratio in perturbative QCD approach based on k T factorization theorem. We find that the branching ratio of this decay is about of order 10^－8, which may be sensitive to new physics.
