Freezeout of resonances and nuclear fragments at RHIC

Abstract

We quantify the conditions at which ``composites'', the resonances and bound states $d,H{e}^3$ are produced at RHIC. Using Hubble-like model for late stages, one can analytically solve the rate equations and also calculate the relevant optical depth factors. We calculate also the modification of $\rho$ masse and width, and predict a radiacal shape change of $\sigma$.
