On the nature of the newly discovered ${\Omega }_c^0$ states

Abstract

The masses and residues of the radially excited heavy ${\Omega }_c^0$ and ${\Omega }_b^{-}$ baryons with spin-parity $J^P={\frac{1}{2}}^{+}$ and $J^P={\frac{3}{2}}^{+}$ are calculated by means of QCD two-point sum rule method using the general form of their interpolating currents. In calculations the quark, gluon and mixed vacuum condensates up to ten dimensions are taken into account. In ${\Omega }_c^0$ channel a comparison is made with the narrow excited states recently observed by the LHCb Collaboration.
