From the full stopping scenario, the dilepton production in the baryon rich quark gluon fireball based on a relativistic hydrodynamic model is studied, and it is found that with increasing incident energy a characteristic plateau indicating the formation of the baryon rich quark gluon matter appears in the total yield.
