Dilepton from Quark-Gluon Plasma and Quark-Hadron Phase Transition
Abstract
A model of statistical quark-gluon plasma formation is considered.We look the dilepton production at critical temperature Tc170 Mev and completely free out temperature T=150 MeV with the initial temperature as T0=570,400 (250) MeV. Now we consider that quark mass is depending on the coupling value through parameterisation factor of the fireball formation and temperature. The rate of production is shown for invariant mass M at the particular value of E=2.0,3.0 GeV.It shows the significant production of leptons in this process for small value of invariant mass. However, the quark-hadron phase transition is a very weakly changed in the entropy of the system during this process of hadronisation.
