    "abstract": "The thermal and nonthermal pion production by sigma decay and its relation\nwith chiral symmetry restoration in a hot and dense matter are investigated.\nThe nonthermal decay into pions of sigma mesons which are popularly produced in\nchiral symmetric phase leads to a low-momentum pion enhancement as a possible\nsignature of chiral phase transition at finite temperature and density.",
