Abstract
Production rates of dileptons and photons from the quark-gluon (QGP) phase are calculated taking into account effects of confinement and spontaneous chiral symmetry breaking () not far from the transition temperature . We find that the production rates of dileptons with large momenta and of photons originating from the QGP around are suppressed by the effect. We also discuss to what extent information about details of the chiral transition, such as its characteristic temperature range and the steepness of the crossover, are reflected in these quantities.
