Inclusive cross section measurement of cumulative proton production in π-(K-,p-bar)Be interactions at 40 GeV/c

Inclusive cross-sections measurement results of the cumulative protons production in π-(K-, p-bar)Be interaction at 40 GeV/c are presented. The data obtained demonstrate the exponential decrease of cross sections in the kinetic energy range 0.1-0.3 GeV with the slope of 44-48 MeV. The total number of the detected cumulative protons in the investigated range of kinetic energies is 1314 from π-, 603 from K-, and 163 from p-bar. The ratios of the cross sections for different types of incident particles have been obtained. Their average values in the energy region under invesigation are (fK/fπ)=0.95±0.05±0.03, (fp-bar/fπ)=2.23±0.19±0.13
