Cold isospin asymmetric baryonic rich matter in nonlocal NJL-like models

Published 21 Feb 2024 in hep-ph | (2402.13842v1)

Abstract: We study the features of low energy strong interactions for a system at zero temperature and finite baryon and isospin chemical potentials, in the framework of a Nambu--Jona-Lasinio-like model that includes nonlocal four-point interactions. We analyze the phase transitions corresponding to chiral symmetry restoration and pion condensation, comparing our results with those obtained from local NJL-like models and lattice QCD calculations.
