Abstract
The inclusive inelastic processesK + p→pX + andK + p→Δ ++ X 0 are studied at an incident momentum of 70 GeV/c. The data comes from the Big European Bubble Chamber BEBC filled with hydrogen, exposed to an rf reparatedK + beam at the CERN SPS accelerator. The inclusive cross section for protons with laboratory momentump LAB≦1.2 GeV/c is equal to (6.1±0.1) mb. InclusiveΔ ++-production is studied for |t p, Δ|<1.0(GeV/c)2. Comparisons are made with otherK + p data and withpp data at 69 GeV/c. Evidence is found for Pomeron exchange at the beam vertex both for slow proton andΔ ++-production as well as for absorptive pion exchange at the (p,Δ ++) vertex.
