The meson degrees of freedom provide the mean field chiral- and isospin-condensates on top of which we compute the effective potential accounting for constituent quark fluctuations at one-loop order. Using the renormalizability of the model, we absorb the ultraviolet divergences into suitable counter-terms that are added respecting the original structure of the theory. These counter-terms are determined from the stability conditions which require the effective pot","authors_text":"Alejandro Ayala, Aritra Bandyopadhyay, Jos\\'e Luis Hern\\'andez, Luis A.
