Abstract
The Delta(++)-resonance production in central 158 A GeV Pb-208 + Pb-208 col lisions at the CERN SPS has been studied. The Delta(++) production was esti mated from the invariant mass spectrum of p pi(+)-pairs by subtracting a mi xed event background. The measured Delta(++) abundance is compared with the results from other experiments at lower energies, and with a model calcula tion assuming thermal and chemical equilibrium.
