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. (C) 2000 Elsevier Science B
