Phys. Rev. Lett. 93, 162301 (2004) [4 pages]Photon Interferometry of Au+Au Collisions at the BNL Relativistic Heavy-Ion ColliderReceived 19 April 2004; revised 10 August 2004; published 13 October 2004 We calculate the two-body correlation function of direct photons produced in central Au+Au collisions at the Relativistic Heavy-Ion Collider. Our calculation includes contributions from the early preequilibrium phase in which photons are produced via hard parton scatterings as well as radiation of photons from a thermalized quark-gluon plasma and the subsequent expanding hadron gas. We find that high energy photon interferometry provides a faithful probe of the details of the space-time evolution and of the early reaction stages of the system. © 2004 The American Physical Society URL:
