Perturbative QCD study of $B_{(s)}\to \varphi \rho$ decays

Abstract

We study $B_{(s)}\to \varphi \rho$ decays in a perturbative QCD approach based on $k_T$ factorization. In this approach, we calculate factorizable and non-factorizable contributions, there are no annihilation contributions due to quark content. We get the branching ratios and polarization fractions for $B_{(s)}\to \varphi \rho$ decays . Our predictions are consistent with the current experimental data.
