Equation of state and transverse expansion effects in heavy ion collisions

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The effects of the equation of state on the expansion of hadronic matter and on the dilepton production rates in heavy ion collisions are studied. We have used two widely different descriptions of the hadron phase and considered scenarios with and without phase transition. The hadron phase is treated either as a gas of ideal massless pions or, more realistically, as a gas of different kinds of massive hadrons with finite size.

In the case of the hadron gas, the lifetime of the mixed phase is considerably reduced and the strength of transverse flow is enhanced. The properties of the equation of state are also reflected in dilepton spectra. In particular, the mass spectra which are obtained with the hadron gas equation of state differ clearly if the phase transition is assumed to occur or not.
