Abstract.

The rare decay \(B^+ \to D_s^+ \phi\) 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 \(B^+ \to D_s^+ \phi\) 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.
