B0 and Bs0 decays into J /ψ plus a scalar or vector meson

Abstract

We extend a recent approach to describe the B0 and Bs0 decays into J/ψ f0(500) and J/ψ f0(980), relating it to the B0 and Bs0 decays into J/ψ and a vector meson, φ, ρ, K∗. In addition, the B0 and Bs0 decays into J/ψ and κ(800) are evaluated and compared to the K∗ vector production. The rates obtained are in agreement with the available experiment while predictions are made for the J/ψ plus κ(800) decay.
