Measurements of production and inelastic cross sections for $mbox{p}+mbox{C}$, $mbox{p}+mbox{Be}$, and $mbox{p}+mbox{Al}$ at 60 GeV/$c$ and $mbox{p}+mbox{C}$ and $mbox{p}+mbox{Be}$ 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 was performed using the NA61/SHINE spectrometer at the CERN SPS. First measurements were obtained using protons at 120 GeV/$c$, while the results for protons at 60 GeV/$c$ were 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.
