Pion production in a field theoretic description of hot compressed matter.

Pion yields are computed from the pion and delta populations found in a field theoretic description of hot dense matter. Two different prescriptions for the initial conditions are considered and the results of a quasihydrodynamic expansion are also studied. It is found that the yield and the slope of pion yield as a function of energy, which are functions of the chemical freeze-out density, might possibly provide a means of determining that density. However, the dependence on the compression modulus of the corresponding cold matter is found to be very low in this model.
