Nonequilibrium Photons as a Signature of Quark-hadron Phase Transition
arXiv:hep-ph/9812220 · doi:10.1016/S0370-2693(99)00092-1
Abstract
We study the nonequilibrium photon production in the quark-hadron phase transition, using the Friedberg-Lee type solitons as a working model for quark-hadron physics. We propose that to search for nonequilibrium photons in the direct photon measurements of heavy-ion collisions may be a characteristic test of the transition from the quark-gluon to hadronic phases.
