The effects of resonance decays on particle ratios and momentum spectra

A Hadron Gas model, including resonance decays, is used to predict momentum spectra and particle ratios. The model, including all significant two and three body resonance decays, is compared with transverse momentum spectra from the CERN-SPS NA44 Pbr Pb experiment and the implications of the fits are discussed. It is shown that resonance decays fail to explain the low mT anomaly in the pion transverse momentum spectrum. The effects of resonance decays are then considered in the calculation of various particle ratios. The width of the rapidity window is varied and its effect on the particle ratios is examined.
