Abstract The inclusive proton diffraction dissociation cross sections in 16, 32, and 110 GeV/cK − p interactions are determined from the spike nearx=1 in the inclusive negative particle spectra and are compared to those obtained inK−p interactions using other selection methods at various energies. The same procedure is applied to events containing aV 0 in order to obtain the cross section for diffractive $$s\bar s$$ production. While the total cross section for proton diffraction is found to be approximately constant in the energy range studied here, proton diffraction yielding an $$s\bar s - pair$$ is found to increase significantly. In particular it is almost constant at 85 μb forΛ 0 and Σ production but for $$NK\bar K$$ it rises from zero at 16 GeV.c to about 200 μb at 110 GeV/c. From the result for $$s\bar s$$ diffractive production an estimate for the $$c\bar c$$ diffractive production cross section of approximately 1–10 μb at 110 GeV/c is obtained.
