$B_s\to K^{\ast 0}$ decay form factors from covariant confined quark model

Abstract

We evaluate $B_s\to K^{\ast 0}$ transition form factors in the full kinematical region within the covariant confined quark model. The calculated form factors can be used to calculate the $B_s\to K^{\ast 0}{\mu }^{+}{\mu }^{-}$ rare decay branching ratio, which was recently measured by LHCb collaboration.
