Inelastic cross sections have been measured for H, Be, C and Bi targets using proton beams at momenta of 58, 85 and 120 GeV/c using the MIPP experiment at Fermilab. The cross section dependence on the atomic weight (A) of the targets has been found to vary as A$$^{\alpha}$$, where $$\alpha$$ is 0.75 $$\pm$$ 0.03 for a beam momentum of 58 GeV/c and 0.66 $$\pm$$ 0.03 for 120 GeV/c. The MIPP data have been compared with the Monte Carlo (DPMJET/FLUKA) predictions and previous measurements. Inelastic cross sections have also been measured as a function of multiplicity for H and C targets using proton beams at different momenta. The DPMJET/FLUKA multiplicity shapes disagree with those of data. Inclusive charged pion production cross sections have also been measured in bins of true momentum for C target using 58 and 120 GeV/c proton beams, and compared with the FLUKA Monte Carlo.
