摘要：

A calculation of the K and pi-masses at finite temperature in the Nambu-Jona-Lasinio model suggests that the phase space for the pi --> KK decay channel disappears for moderate values of the temperature. We discuss the relevance of this effect for the interpretation of dilepton production in high-energy nuclear collisions.
