Thermal photons to dileptons ratio at LHC
arXiv:0705.3505
Abstract
It is shown that the ratio of transverse momentum (p_T) distribution of thermal photons to dileptons produced in heavy ion collisions reaches a plateau above p_T=1 GeV. We argue that the value of the ratio in the plateau region can be used to estimate the initial temperature.
