文摘Considered the Drell-Yan background in the intermediate invariant mass region,the dilepton production in an expanding hot baryon-rich quark-gluon matter fire-cylinder hasbeen studied based on a previously established rclativistic hydrodynamic model. It is foundthat with increasing the rapidity the dilepton yield is strongly suppressed. Such a characteristic, signaling the formation of the baryon-rich quark-gluon matter, can be tested in futureexperiments at Brookhaven and CERN.
