Deltas in hadron gas
Description
The relation between the author's transport theory approach to the systems with unstable particles and the S-matrix formulation of statistical mechanics is established. Then, the equilibrium characteristics of a classical gas of nucleons, deltas, and pions are studied. The finiteness of the delta decay width is taken into account. It is shown that if one treats the delta isobars as stable particles their number is significantly underestimated at the temperatures smaller than about 60 MeV
