${\bar{B}}^0$ and ${\bar{B}}_s^0$ decays into $J/\psi$ and $f_0(1370),f_0(1710),f_2(1270),f_2^{\prime }(1525),K_2^{\ast }(1430)$

Abstract

We make predictions for the ratios of branching fractions of ${\bar{B}}^0$ and ${\bar{B}}_s^0$ decays into $J/\psi$ and the scalar mesons $f_0(1370),f_0(1710)$ or tensor mesons $f_2(1270),f_2^{\prime }(1525),K_2^{\ast }(1430)$. The theoretical approach is based on results of chiral unitary theory where these resonances are shown to be generated from the vector meson-vector meson interaction. Eight independent ratios can be predicted and comparison is made with the recent data on ${\bar{B}}_s^0$ decay into $J/\psi f_2^{\prime }(1525)$ versus the ${\bar{B}}_s^0$ decay into $J/\psi f_2(1270)$.
