Evidence of the \(h_c\to K_S^0 K^+π^-+c.c.\) decay

By Besiii Collaboration and others
Based on \((2.712\pm0.014)\times10^9\) \(\psi(3686)\) events collected by the BESIII collaboration, evidence of the hadronic decay \(h_c\to K_S^0K^+\pi^-+c.c.\) is found with a significance of \(4.3\sigma\) in the \(\psi(3686)\to\pi^0 h_c\) process. The branching fraction of \(h_c\to K_S^0 K^+\pi^- +c.c.\) is measured to be \((7.3\pm0.8\pm1.8)\times10^{-4}\), where the first and second uncertainties are statistical... Show more
