The rare decay B^+ \to D_s^+ \bar K^{*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 found that the branching ratio of this decay is about of order 10^{-8}, which may be sensitive to new physics.

Enhanced Quark-Loop Contribution to Pure Annihilation Nonleptonic B-meson decays in PQCD approach
Quark-loop NLO corrections to pure annihilation B decays leave branching ratios nearly unchanged but significantly enhance direct and mixing-induced CP asymmetries, with Bd to phi phi reaching about -40 percent.
