Pion Damping width from SU(2)xSU(2) Nambu-Jona-Lasinio model

Within the framework of the Nambu-Jona-Lasinio model, we investigate the modification of the pion damping width in a hot pion gas for the temperatures ranging from 0 to 180 MeV. The pion is found to broaden noticeably at T > 60 MeV. Near the chiral phase transition T approx 180 MeV, the pion widt...
