Abstract

The W-exchange process B s η c (J/ψ)D is studied with the perturbative QCD approach. Three kinds of wave functions for B s meson and two forms of wave functions for charmonium are considered. It is estimated that the branching ratios for \(B_{s}\to{\eta}_{c}\overline{D}\), η c D, \(J/{\psi}\overline{D}\), J/ψD decays are of the order of 10−7, 10−8, 10−8, 10−9, respectively, where the largest uncertainty is from wave functions. There is a possibility for measuring these decays in the near future.
