Measurements of production and inelastic cross sections for p +C , p +Be , and p +Al at 60 GeV /c and p +C and p +Be at 120 GeV /c

This paper presents measurements of production cross sections and inelastic cross sections for the following reactions: 60 GeV /c protons with C, Be, Al targets and 120 GeV /c protons with C and Be targets. The analysis is performed using the NA61/SHINE spectrometer at the CERN Super Proton Synchrotron. First measurements are obtained using protons at 120 GeV /c , while the results for protons at 60 GeV /c are compared with previously published measurements. These interaction cross section measurements are critical inputs for neutrino flux prediction in current and future accelerator-based long-baseline neutrino experiments.
