Heavy quark dominance and fine structure of excited heavy baryons $\Sigma_{Q}$, $\Xi '_{Q}$ and $\Omega_{Q}$
In the framework of the relativized quark model, the calculation of spin-orbit interactions is improved by considering the contribution from the light quark cluster in a singly heavy baryon. It enhances the energy level splitting of the orbital excitation and causes a partial removal of the energy level degeneracy and …
