Abstract
We study the nonequilibrium photon production in the quark-hadron phase tra nsition, using the Friedberg-Lee type solitons as a working model for quark -hadron physics. We propose that to search for nonequilibrium photons in th e direct photon measurements of heavy-ion collisions may be a characteristi c test of the transition from the quark-gluon to hadronic phases.
