Abstract

We consider the weak decays of a B meson to final states that contain a S-wave radially excited vector meson. We consider vector-pseudoscalar final states and calculate ratios of the type Bρπ/BρπB \to \rho^{\prime} \pi/B \to \rho \pi, Bωπ/BωπB \to \omega^{\prime} \pi/B \to \omega \pi and Bϕπ/BϕπB \to \phi^{\prime} \pi/B \to \phi \pi where ρ\rho^{\prime}, ω\omega^{\prime} and ϕ\phi^{\prime} are higher ρ\rho, ω\omega and ϕ\phi S-wave radial excitations. We find such decays to have larger or similar branching ratios compared to decays where the final state ρ\rho, ω\omega and ϕ\phi are in the ground state. We also study the effect of radial mixing in the vector system generated from hyperfine interaction and the annihilation term.
