Inclusive production of the Δ (1232) resonance has been measured in 280 GeV/c muon-proton interactions. The production of the Δ++ as a function of the variables χBJ, W, Q2, χF and pT2 is investigated. The average Δ++ multiplicity is found to be smaller, by a factor of 6.2 ± 1.2, than the average multiplicity of protons. An upper limit for Δ0 production is obtained. The net hadronic charge distribution for events with a Δ++ is presented. The results are compared to the predictions of the Lund and Fire string models. © 1986.
