Inclusive single and double diffractive dissociations inK+p interactions at 32 GeV/c

AbstractWe study single and double inclusive diffractive production in a 32 GeV/c K+p experiment in MIRABELLE at the Serpukhov accelerator. From reactionsK+p→K++X+ andK+p→X++p we determine the total proton and kaon single diffractive dissociation cross sections

. 90±0.17 mb, respectively. In either case the only notable contributions come from dissociations into 1 and 3 charged particles. Kaon dissociation exhibits a pronounced slope-mass correlation. The search for double diffractive production in reactionsK+p→(K+π−π+)+X+ andK+p→(pπ+π−)+X+ leads in either case to an estimated total double diffractive cross section σ(K+p→KD+pD) of ≅220 μb. The double dissociation differential cross section exhibits a large slope of ≅10GeV−2 in the nearthreshold mass region, rapidly decreasing to ≅4 GeV−2 with increasing excitation mass.
