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

Abstract

We study $B_{\small (s)}\to \phi\rho$ 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 $B_{\small (s)}\to \phi\rho$ decays . Our predictions are consistent with the current experimental data.
