Calculation of pure annihilation type decay B+→Ds+φ
Description
The rare decay B+→Ds+φ can occur only via annihilation-type diagrams in the standard model. We calculated this decay in the perturbative QCD approach with Sudakov resummation. We found that the branching ratio of B+→Ds+φ is of order 10-7; this may be measured in the near future by the KEK and SLAC B factories. The small branching ratio predicted in the standard model makes this channel sensitive to new physics contributions. (orig.)
