Description
Electromagnetic radiation off strongly interacting matter resulting from ultrarelativistic heavy-ion collisions is estimated. We consider virtual photons (dileptons) and real photons produced in the course of cooling thermalized matter. The chemical evolution of initially undersaturated parton matter coupled to the longitudinal and transverse expansion is followed. Due to the strong transverse expansion the socalled M perpendicularto scaling is restored. Some estimates of contributions of the pre-equilibrium stage are presented. (orig.)
