Heavy Baryon Masses in Large Nc HQET


We argue that in the large Nc HQET, the masses of the s-wave lowspin heavy baryons equal to the heavy quark mass plus proton mass approximately. To the subleading order, the heavy baryon mass 1/Nc 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.
