Photon interferometry and size of the hot zone in relativistic heavy ion collisions

Abstract

The parameters obtained from the theoretical analysis of the single photon spectra observed by the WA98 collaboration at SPS energies have been used to evaluate the two photon correlation functions. The single photon spectra and the two photon correlations at RHIC energies have also been evaluated, taking into account the effects of the possible spectral change of hadrons in a thermal bath. We find that the ratio $R_{side}/R_{out}\sim 1$ for SPS and $R_{side}/R_{out}<1$ for RHIC energy.
