A Heavy Ion Fireball freeze-out Dipion Cocktail for Au-Au Collisions at
$\sqrt{s_{NN}}$=200 GeV (Part1)    [PDF]

Ron S. Longacre

In this paper we develop all the ingredients that come into play in the freeze-out of the heavy ion fireball for Au-Au collisions at $\sqrt{s_{NN}}$=200 GeV into dipions. The resonance production of particles that decay into dipions plus minijets that also decay into dipions are explored. The final state re-scattering of the pions from minijets play an important role in the mass spectrum of the cocktail. Mass shifts due to minijet interference which depend on the volume of the re-scattering pions is presented. The effective mass balance function is explained. The dipion mass spectrum within a $p_t$ range(intermediate $p_t$) is fitted using thermal and minijet amplitudes.
