Absence of spontaneous parity breaking in strongly interacting matter
Roberto Anglani
Abstract
We have studied some aspects of the pion condensation in a 2-flavor neutral quark matter within the Nambu-Jona-Lasinio (NJL) model of QCD at finite density ? and T = 0. We have investigated the role of some parameters of the model to clarify which of them are responsible for the onset of the pion condensation.
