Weak rare decays for B → ω transitions within covariant confined quark model framework

Abstract

We present the branching fractions for the rare semileptonic decay B→ωl+l− for l=e,μ,τ. The necessary transition form factors are computed in the entire range of momentum transfer within the Standard Model framework of Covariant Confined Quark Model with built-in infra-red confinement. We further compute different physical observables such as forward backward asymmetry, longitudinal and transverse polarization along with other angular observables.
