Particle production measurements using the MIPP detector at fermilab

Abstract

Inelastic cross sections have been measured for H, Be, C and Bi targets using proton beams at momenta of 58, 85 and 120GeV/c using theMIPP experiment at Fermilab. The cross section dependence on the atomicweight (A) of the targets has been found to vary as Aα, where α is 0.75 ± 0.03 for a beam momentum of 58GeV/c and 0.66 ± 0.03 for 120 GeV/c. TheMIPP data have been compared with theMonte 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. TheDPMJET/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 120GeV/c proton beams, and compared with the FLUKA Monte Carlo.
