[en] Results are presented on the inclusive scattering process a + p → c + X where a and c are any of π^+-, K^+-, p or anti p. The data were taken at 100 and 175 GeV/c incident momentum using the Fermilab Single Arm Spectrometer. A vertex detector was also used to measure the associated charged multiplicity. The x dependences of the inclusive cross section exhibit the power law behavior expected from various fragmentation models. 12 references

[en] Measurements of inclusive cross sections at 100 GeV/c are presented for the double-charge-exchange reactions a⁺p → π^-X with a = π, K, or p. The measurements covered a kinematic range in the Feynman x variable of 0.3 < or = x < or = 0.9 at transverse momenta of 0.3 and 0.5 GeV/c. A model summing the contributions from resonance production and from inclusive central-region π^- production is used to fit the data and demonstrates the importance of resonance production via one-pion exchange for large values of the Feynman x
