Abstract：
Considered the Drell-Yan background,the rapidity dependenec of the dilepton production in the baryon-rich quark-gluon matter from ¹⁹⁷Au+ ¹⁹⁷Au cental collision has been studied based on a relativistic hydrodnamic model. It is found that the dilepton yield is strongly suppressed with increasing rapidity.Such a characteristic signaling the formation of the baryon-rich quark-gluon matter can be tested in future experimentS at CERN and Brookhaven.
