Spectrum of strange singly charmed baryons in the constituent quark model

Abstract

Excited states masses of the strange singly charmed baryons are calculated using the non-relativistic approach of hypercentral Constituent Quark Model (hCQM). The hyper-Coulomb plus screened potential is used as a confinement potential with the first order correction. The spin-spin, spin-orbit and spin-tensor interaction terms are included perturbatively. Our calculated masses are allowed to construct the Regge trajectories in both $(n_r,M^2)$ and $(J,M^2)$ planes. The mass spectra and the Regge trajectories study predict the spin-parity of $\Xi {}_c(2970{)}^{+/0}$, $\Xi {}_c(3080{)}^{+/0}$, $\Xi {}_c(3123{)}^{+}$, $\Omega {}_c(3000{)}^0$ and $\Omega {}_c(3119{)}^0$ baryons. Moreover, the strong one pion decay rates of the isodoublet states of $\Xi {}_c(2645)$, $\Xi {}_c(2790)$ and $\Xi {}_c(2815)$ are analyzed in the framework of Heavy Hadron Chiral Perturbation Theory (HHChPT). Also, the ground state magnetic moments and the radiative decay rates based on the transition magnetic moments are calculated in the framework of constituent quark model.
