PHOTON INTERFEROMETRY OF QUARK-GLUON DYNAMICS

Two-photon intensity interferometry is used as a probe of the dynamics of quarks and gluons in a high energy nucleus-nucleus collision. Unde r the assumption that transverse expansion of hadrons in the final sta te is not important, we show that the correlation of high transverse-m omentum photons is sensitive to the details of the space-time evolutio n of the high density QCD plasma. This is in contrast to hadron interf erometry, which is sensitive mainly to the later dilute stage of the r eaction.
