Abstract: (Elsevier)
The influence of resonance decays on hadronic momentum spectra is studied quantitatively within a simple thermodynamical model. We derive expressions for the rapidity and transverse momentum spectra of particles originating from two- and three-body decay of resonances with specified momentum distribution. We compare the results for a thermally and chemically equilibrated hadron gas without transverse expansion with data from the NA35 Collaboration for pion, kaon, proton and Λ p T spectra from 200 A GeV S + S collisions and find excellent agreement for T = 200 MeV and μ b = 100–200 MeV.- scattering: heavy ion
