Revisit assignments of the new excited $$\Omega _c$$ Ω c states with QCD sum rules
Abstract In this article, we distinguish the contributions of the positive parity and negative parity $$\Omega _c$$ Ω c states, study the masses and pole residues of the 1S, 1P, 2S and 2P $$\Omega _c$$ Ω c states with the spin $$J=\frac{1}{2}$$ J = 1 2 and $$\frac{3}{2}$$ 3 2 using the QCD sum rules...
