Measuring initial temperature through photon to dilepton ratio in heavy ion collision

Nuclear Theory 2008-11-26 v2

Abstract

Theoretical calculation of transverse momentum(pTp_T) distribution of thermal photons and dileptons originating from ultra-relativistic heavy ion collisions suffer from several uncertainties since the evaluation of these spectra needs various inputs which are not yet known unambiguously. In the present work the ratio of the pTp_T spectra of thermal photons to lepton pairs has been evaluated and it is shown that the ratio is insensitive to some of these parameters.
