Pion and thermal photon spectra as a possible signal for a phase transition

High Energy Physics - Phenomenology 2009-09-25 v1

Abstract

We calculate thermal photon and neutral pion spectra in ultrarelativistic heavy-ion collisions in the framework of three-fluid hydrodynamics. Both spectra are quite sensitive to the equation of state used. In particular, within our model, recent data for S+AuS+Au at 200200 AGeV can only be understood if a scenario with a phase transition (possibly to a quark-gluon plasma) is assumed. Results for Au+AuAu+Au at 1111 AGeV and Pb+PbPb+Pb at 160160 AGeV are also presented.
