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

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 perturbative QCD approach based on $k_T$ factorization. With the referenced value of the mixing angle $|\va...
