$B\to \rho$ Decay Form Factors from Covariant Confined Quark Model

Abstract

We evaluate $B\to \rho$ transition form factors in the full kinematical region within the covariant confined quark model. We compare the obtained results with the results from light-cone sum rules. The calculated form factors can be used to calculate the $B^{+}\to {\rho }^{+}{\mu }^{+}{\mu }^{-}$ rare decay branching ratio.
