Heavy Baryon Masses in Large N_c HQET

High Energy Physics - Phenomenology 2015-06-25 v1

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.
