Calculation of Rare Decay B+ Ds+ K*0 in Perturbative QCD Approach
Abstract
The rare decay B+ Ds+ K*0 can occur only via annihilation diagrams in the Standard Model. We calculate the branching ratio in perturbative QCD approach based on kT factorization theorem. We found that the branching ratio of this decay is about of order 10-8, which may be sensitive to new physics.
