Single-photon distributions and two-photon correlations in central rapidity region have been calculated for heavy ion collisions at high energies. It has been found that opposite side two-photon correlations can serve as a sign of sharp transitions between the states of strongly interaction matter.9 pages, no figuresHigh Energy Physics - PhenomenologySoft photon emission as a sign of sharp transition in quark-gluon plasmatext
