Heavy Baryon Masses in Large N_c HQET
arXiv:hep-ph/9611288 · doi:10.1016/S0370-2693(96)01269-5
Abstract
We argue that in the large N_c HQET, the masses of the s-wave low-spin heavy baryons equal to the heavy quark mass plus proton mass approximately. To the subleading order, the heavy baryon mass 1/N_c expansion not only has the same form, but also has the same coefficients as that of the light baryon. Based on this, numerical analysis is made.
