An alternative approach to baryon masses in the $1/N_c$ expansion of QCD

Ruben Flores-Mendieta, Sergio Alejandro Garcia-Monreal, Luis Roman Ruiz-Robles +1

The baryon mass operator is studied within a combined expansion in $1/N_c$ and perturbative $SU(3)$ flavor symmetry breaking, where $N_c$ denotes the number of quark charges. Flavo…
