IS THE THERMAL DILEPTON SPECTRUM A SIGNATURE FOR DIAGNOSING FIRST-ORDER DETONATION QCD PHASE TRANSITION?

Detonation has two different scenarios: the Gyulassy's scenario and the Kapusta's one. The dilepton production rate in the Kapusta's scenario is calculated. Associated with the Gyulassy's scenario, the peculiar property of the spectrum and its dynamical origin in the detonation phase transition are discussed and analyzed. Its spectrum is not a signature for diagnosing the detonation phase transition.
