OPEN CHARM, PHOTON, AND DILEPTON PRODUCTION IN AN INCREASINGLY STRONGLY INTERACTING PARTON PLASMA

We examine the effects that the new equilibration scenario of the incr easingly strongly interacting parton plasma and the nonequilibrium env ironment have on the production of open charms, photons, and dileptons at Large Hadron Collider (LHC) and at Relativistic Heavy Ion Collider (RHIC) energies. We show that an out-of-equilibrium effect, not shown before, changes significantly the relative yield of the two main part onic contributions to photon production in the higher p(T) range, and higher orders for electromagnetic emissions have increased significanc e in the new scenario especially at RHIC energies. We argue that the e ffects of the new scenario are not restricted just to the parton phase but will continue through to the later hadron gas phase with potentia lly positive implications for the detection of the quark-gluon plasma.
