    "abstract": "Within the framework of the NJL model, we investigate the modification of the\npion damping width in a hot pion gas for temperatures ranging from 0 to 180\nMeV. The pion is found to broaden noticeably at T \u003e 60 MeV. Near the chiral\nphase transition T ~ 180 MeV, the pion width is saturated and amounts to 70\nMeV. The main contribution to the width comes from pion-pion collisions. Other\ncontributions are found negligibly small.",
