Selected strong decays of pentaquark State $P_c(4312)$ in a chiral constituent quark model

19 Feb 2020 Dong Yubing Shen Pengnian Huang Fei Zhang Zongye

The newly confirmed pentaquark state $P_c(4312)$ has been treated as a weakly bound $(\Sigma_c\bar{D})$ state by a well-established chiral constituent quark model and by a dynamical calculation on quark degrees of freedom where the quark exchange effect is accounted for. The obtained mass $4308$ MeV agrees with data... (read more)
