Investigation of the mass spectra of singly heavy baryons ${\Sigma }_Q$, ${\Xi }_Q^{\prime }$ and ${\Omega }_Q$ $(Q=c,b)$ in the Regge trajectory model

Very recently, LHCb Collaboration observed that two new ${\Omega }_c^0$ states decay into ${\Xi }_c^{+}{K}^{-}$ with masses of about $3185$ MeV and $3327$ MeV. However, their spin parity qu…
