THERMAL PHOTONS AND DILEPTONS FROM NONEQUILIBRIUM QUARK-GLUON PLASMA

The dependence on initial conditions of thermal production rates for p hotons and dileptons in the quark-gluon plasma is discussed. We also c onsider using these signals to experimentally determine plasma initial conditions. Based on the chemical rate equations of Biro et al., we s how that later emissions in the thermal expansion conceal information about the initial conditions in the region of low p(T) and M, making d etermination of initial conditions difficult.
