Abstract
Using a Hagedorn resonance gas picture and quark-hadron
duality we estimate the dilepton emission rate in the vicinity of
the QCD deconfinement phase transition. The result is then used to
calculate a dilepton spectrum in ultrarelativistic heavy ion
collisions. We show that multibody contributions taken into account in
the Hagedorn resonance gas approach provide an enhancement of
the production rate massive dileptons
as compared to the previously considered sources.
