Description

Results are presented on K+ p elastic scattering and on the reaction K+ p→K+ pπ+π- at 70 GeV/c. For the elastic channel, we measured the total ((2.29+-0.04)mb) and differential dsigma/dt cross sections. The reaction K+ p→K+ pπ+π- has a total cross section of (470+-23)μb and is shown to be dominated by diffractive dissociation processes. The contributions of the quasi-two-body channels K+ p→Ksup(*)0(890)Δ++(1,236) and K+ p→Ksup(*)0(1,430)Δ++(1,236) and of the Double-Pomeron Exchange (DPE) processes are estimated. (orig.)
