In general, the spectrum of lepton pairs produced in nuclear reactions depends on both invariant mass and momentum. But under a few reasonable assumptions on the time evolution of the system, we show that once the quark-gluon plasma is created in ultrarelativistic heavy ion collisions, the observed dilepton spectrum between the [phi] and [ital J]/[psi] peak becomes dependent essentially only on its transverse mass [ital M][sub [ital T]] and thus shows [ital M][sub [ital T]] scaling. This scaling will not be observed if the quark-gluon plasma is not created in collisions.
