$P_c$ resonances are studied in the approach of quark model and group theory. It is found that there totally 17 possible pentaquark states with contents $q^3Q \bar Q$ ($q$ $u$ $d$ quarks; $Q$ $c$ quark) compact picture, where hidden heavy may take color singlet-singlet ($[111]_{{qqq}}\otimes [111]_{{c c}}$) octet-octet ($[21]_{{qqq}}\otimes [21]_{{c configurations. The partial decay widths calculated for all channels. results show $pJ/\psi$ dominant channel both spin $3/2$ $1/2$ states,...

Hidden-charm pentaquarks are analysed in Group Theory the baryon-meson molecule picture within framework of constituent quark model. The investigation strong decays pentaquark resonances reveals that states all configurations can decay through $N J/\psi$ channel while only five may open-charm modes. partial widths $p\eta_c$ same order as $p for $J^P=1/2^-$ states, but is forbidden $J^P=3/2^-$ states. \eta_c$, $\Sigma_c\bar{D}$ and $\Lambda_c^+\bar{D}$ channels open $P_c(4440)$ $P_c(4457)$...
We systematically study hidden charm pentaquark states in the constituent quark model with a general Hamiltonian for multiquark systems, considering coupling between $\Sigma_c^{(*)}\bar{D}^{(*)}$ molecular and $q^3c\bar c$ compact by one-gluon exchange hyperfine interaction. The ground state hidden-charm mass spectra strong decay widths are calculated. This work suggests that $P_c(4312)$, $P_c(4457)$ $P_c(4380)$ resonances might be mainly $\Sigma_c \bar D$, D^*$ $\Sigma_c^* D$ hadronic...
