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

Abstract

We evaluate $B \rightarrow \rho$ 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 $B^+ \rightarrow \rho^+ {\mu}^+ {\mu}^-$ rare decay branching ratio.
