Measurements of total production cross sections for \(\pi^{+}\)+C, \(\pi^{+}\)+Al, \(K^{+}\)+C, and \(K^{+}\)+Al at 60 GeV/c and \(\pi^{+}\)+C and \(\pi^{+}\)+Al at 31 GeV/c

This paper presents several measurements of total production cross sections and total inelastic cross sections for the following reactions: \(\pi^{+}\)+C, \(\pi^{+}\)+Al, \(K^{+}\)+C, \(K^{+}\)+Al at 60 GeV/c, \(\pi^{+}\)+C and \(\pi^{+}\)+Al at 31 GeV/c . The measurements were made using the NA61/SHINE spectrometer at the CERN SPS. Comparisons with previous measurements are given and good agreement is seen. These interaction cross sections measurements are a key ingredient for neutrino flux prediction from the reinteractions of secondary hadrons in current and future accelerator-based long-baseline neutrino experiments.
