Abstract
The dilepton radial flow in Au+Au collisions at sNN=200 GeV is investigated. The space-time evolution of the fireball is described by a 2+1 dimensional ideal hydrodynamics with a variety of equations of state. The slope parameters of the transverse momentum spectra from the partonic and hadronic phases show distinct features and are sensitive to equation of state parameters. The elliptic flow and breaking of MT scaling are also studied and have distinct features for the two phases. These features can serve as clean signals for the formation of a quark-gluon plasma in ultra-relativistic heavy ion collisions.
