Description
From the full stopping scenario, a relativistic hydrodynamic model describing the evolution of the baryon-rich quark-gluon matter fire-cylinder has been established. Based on it, the rapidity distribution of dileptons with intermediate invariant masses has been studied. It is found that the quark phase gives the dominant contribution to the dilepton spectrum due to the influence of the phase boundary on the evolution of the system, especially the dilepton yield is strongly suppressed with the increasing rapidity
