Abstract

We investigate the effects of flavor dependence on the rare weak decays of $B_c^{*}$ and $B_s^{*}$ mesons to psuedoscalar and vector mesons in the final state. We use the Bauer-Stech-Wirbel model framework to calculate the flavor dependent effects of transverse quark momentum on the form factors and consequently, the branching ratios of Cabibbo-Kobayashi-Maskawa favored and suppressed modes by employing the factorization hypothesis. We find that the flavor dependent effects significantly enhance the form factors and, consequently, the branching ratios. Some of the decay channels in $B_c^{*}$ and $B_s^{*}$ have branching ratios $\mathcal{O}(10^{-5})$ to $\mathcal{O}(10^{-7})$ , which are well within the reach of current experiments.
