How to probe the Pre-equilibrium stage and Phase Transitions of Quark-Matter by Photon-Interferometry

摘要

We study the single- and double-inclusive spectra of thermal photons, produced in heavy-ion collisions at -/s = 200 AGeV within a realistic space-time frame-work. Pre-equilibrium effects are taken into account. We discuss the possibility of photon-interferometry serving as a a new signature of the deconfinement-phase-transition. Moreover, its sensitivity to the space-time development of the source is investigated in detail.
