Search for the ${\eta }_c(2S)/h_c\to p\bar{p}$ decays and measurements of the ${\chi }_{cJ}\to p\bar{p}$ branching fractions

BESlll Collaboration, M. Ablikim, M. N. Achasov +374

Using a sample of $1.06\times 10^8\psi (3686)$ events collected with the BESIII detector at BEPCII, the decays ${\eta }_c(2S)\to p\bar{p}$ and $h_c\to p\bar{p}$ are searched for, where…
