摘要：

Hadronization at finite temperature T is discussed in the framework of the Nambu-Jona-Lasinio model. The differential cross-section for the conversion of a quark-antiquark pair into two pions to first order in a 1/N-c expansion is calculated as a function of the c.m. energy s and temperature T. In particular, approaching the temperature T-c of the chiral phase transition, the hadronization cross-section diverges like In /1 - T/T-c/.
