A signature for the formation of the quark-gluon plasma in relativistic nucleus-nucleus collisions

From thermodynamic relations, the initial values of the quark-gloun plasma from relativistic nucleus-nucleus collisions are obtained. From these initi al values we have studied the dilepton production on the basis of the (3 1) dimensional relativistic hydrodynamic model established by the present a uthors, and found that with increasing incident energy a characteristic pla teau indicating the formation of quark-gluon plasma appears in the total yi eld, which may be tested in future experiments in CERN and Brookhaven.
