Branching ratios and CP asymmetries of $B^0\to {\eta }_c{f}_0$ in the improved perturbative QCD formalism

Min-Qi Li, Xin Liu, Zhi-Tian Zou +2

Motivated by the idea of fragmented scalar glueball, we investigate the decays $B^0\to {\eta }_c{f}_0$ within the improved perturbative QCD (iPQCD) framework by including the known next-…
