The reaction K + p → p + X is studied at a beam momentum of 16 GeV/ c using the events where a slow proton with momentum p lab < 1.2 GeV/ c is identified by its bubble density. The inclusive spectra presented and compared with those obtained in K + p interactions at 32 GeV/ c and K − p interactions at 14.3 GeV/ c . The prominent features associated with a triple-Regge formula are found to be consistent with the data. It is shown that the Δ ++ (1236) production strongly affects the shape of the inclusive spectra and the results of the triple-Regge fit. After removal of events associated with Δ ++ (1236) production, the data are consistent with the dominance of an ffR coupling.

The invariant cross section for the inclusive production of π+, π−, K+, K−, p, and p¯ is presented for proton-nucleon interactions at plab=28.5 GeV/c. Beryllium, titanium, and tungsten targets were used and the yields were extrapolated to A=1 using the power law σ∼Aα. The exponent α increases with pT, except for protons. The pT dependence of the cross sections is compared with a simple fireball model.
