Abstract

The Δ++-resonance production in central 158 A GeV 208Pb + 208Pb collisions at the CERN SPS has been studied. The Δ++ production was estimated from the invariant mass spectrum of π+-pairs by subtracting a mixed event background. The measured Δ++ abundance is compared with the results from other experiments at lower energies, and with a model calculation assuming thermal and chemical equilibrium.

AB - The Δ++-resonance production in central 158 A GeV 208Pb + 208Pb collisions at the CERN SPS has been studied. The Δ++ production was estimated from the invariant mass spectrum of π+-pairs by subtracting a mixed event background. The measured Δ++ abundance is compared with the results from other experiments at lower energies, and with a model calculation assuming thermal and chemical equilibrium.
