Abstract
Two-photon intensity interferometry is used as a probe of the dynamics of quarks and gluons in a high energy nucleus-nucleus collision. Under the assumption that transverse expansion of hadrons in the final state is not important, we show that the correlation of high transverse-momentum photons is sensitive to the details of the space-time evolution of the high density QCD plasma. This is in contrast to hadron interferometry, which is sensitive mainly to the later dilute stage of the reaction.
