Description
The final stage of a relativistic heavy-ion collision is a hadron gas. Final-state interactions therein distort the p_t spectrum of particles coming from the phase transition upon cooling the quark-gluon plasma.
Using recent state of the art parametrizations of pion interactions by Ruiz de Elvira and Peláez we provide theoretical computations of the pionic depth of the gas: how likely is it that a given pion rescatters on its way out (we find a high probability around p_t=0.5 GeV, corresponding to the formation of the rho resonance), how many pions make it through as a function of p_t, and what is the thickness of the freeze-out last scattering surface.
