Phase diagram and pion modes of the neutral Nambu-Jona Lasinio model with the Polyakov loop
arXiv:0805.3942 · doi:10.1143/PTPS.174.60
Abstract
I discuss recent results obtained by our group within the Nambu-Jona Lasinio model with the Polyakov loop. I focus on the two flavor version of the model, discussing the phase diagram in the plane in the case in which electrical neutrality is required. One of the results is that pion condensation is not observed in our model when a physical mass for the light quarks is considered.
