Dependence of the dilepton production in QGP on the incident energy ofcolliding nuclei

Initial values of thequark-gluon plasmasystem from relativistic nucleus-nucleus collisions are discussedunder thermodynamic equilibrium.From these initial values, the dependence ofthe dilepton production on the incident energy of colliding nuclei hasbeen studied basedon the relativistic hydrodynamicmodel, and it is found that with increasing incident energy a characteristic plateauindicating the formation of the quark-gluon plasma appears in the total yield.
