Perturbative QCD analysis of neutral $B$-meson decays into $\sigma \sigma ,\sigma f_0$ and $f_0{f}_0$

Hua-Dian Niu, Guo-Dong Li, Jia-Le Ren +1

The decays of $B_{d,s}^0\to \sigma \sigma ,\sigma f_0,f_0{f}_0$, with $\sigma$ and $f_0$ denoting the light scalar mesons $f_0(500)$ and $f_0(980)$ in the two-quark picture, are studied in the perturba…
