摘要: Abstract Production rates of real and virtual photons from a hot quark-gluon plasma are reviewed with emphasis on recent advances in the perturbative analysis rate calculations for low-mass lepton pairs. Momentum distributions central A+A collisions calculated by convoluting at fixed temperature hydrodynamic expansion produced matter. The possibilities to observed thermal electromagnetic signals considered different parts phase space comparing dominant backgrounds.
