Abstract
The experimental transverse momentum distributions of negative pions produced in dC, HeC, and CC collisions at 4.2 A GeV/ c were analyzed in the framework of Hagedorn Thermodynamic Model. The spectral temperatures of π mesons as well as their relative contributions to the total multiplicity of π mesons were extracted from fitting the p spectra by two-temperature Hagedorn function. The results were compared systematically with the earlier results obtained from analysis of non-invariant center-of-mass energy spectra of negative pions produced in the analyzed collisions.
