The NA24 experiment at CERN investigated inclusive, 00, and 0 final states in the mass range between 4 and 9 GeV/c2 produced in -p, +p, and pp reactions at a c.m.-system energy s=23.7 GeV. The 00 cross sections agree well with expectations of the quark-parton model. For 0 production in -p and pp reactions, a clear signal is observed and cross sections are shown. The production of events was observed with a statistical significance of 2.9 in -p reactions. The cross section is in agreement with a higher-order QCD prediction.
