Suppression of dilepton production at finite baryon density

We study dilepton production from a quark-gluon plasma of given energy density at finite quark chemical potential [mu] and find that the dilepton production rate is a strongly decreasing function of [mu]. Therefore, the signal to background ratio of dileptons from a plasma created in a heavy-ion col...

Description
Summary:We study dilepton production from a quark-gluon plasma of given energy density at finite quark chemical potential [mu] and find that the dilepton production rate is a strongly decreasing function of [mu]. Therefore, the signal to background ratio of dileptons from a plasma created in a heavy-ion collision may decrease significantly.
