Charmless B decays to final states with radially excited vector mesons

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 B → ρ′π/B → ρπ, B → ω′π/B → ωπ and B → ϕ′π/B → ϕπ where ρ′, ω′ and ϕ′ are higher ρ, ω and ϕ S-wave radial excitations. We find such decays to have larger or similar branching ratios compared to decays where the final state ρ, ω and ϕ 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.
