### Description

In 2016, NA61/SHINE, a fixed target experiment at the CERN SPS, recorded interactions of 60 GeV/$c$ $\pi^+$ with thin carbon and beryllium targets. Three analyses were performed to measure total cross sections and doubly differential cross sections of produced hadrons. A total cross section analysis was used to determine the total production and total inelastic cross sections for the two reactions. A V0 analysis was used to measure spectra of the produced neutral hadrons: $K^0_S$, $\Lambda$ and $\bar{\Lambda}$. Finally, a dE/dx analysis was used to measure spectra of the produced charged hadrons: $\pi^+$, $\pi^-$, $K^+$, $K^-$ and protons. These measurements will allow NO$\nu$A, DUNE and other neutrino experiments to constrain their neutrino flux predictions and make more precise measurements of neutrino oscillation parameters.
