Baryon axial vector current in large-$N_c$ chiral perturbation theory: Complete analysis for $N_c=3$

Ruben Flores-Mendieta, Carlos Isaac Garcia, Johann Hernandez

The baryon axial vector current is computed in heavy baryon chiral perturbation theory in the large-$N_c$ limit, where $N_c$ is the number of color charges. One-loop nonanalytic co…
