Abstract

This paper presents the multiplicity of neutral and charged hadrons produced in $90 GeV / c$ proton-carbon interactions from a dataset taken by the NA61/SHINE experiment in 2017. Particle identification via $d E / d x$ was performed for the charged hadrons $π^{\pm}$ , $K^{\pm}$ , and $p / \bar{p}$ ; the neutral hadrons $K_{S}^{0}$ , $Λ$ , and $\bar{Λ}$ were identified via an invariant mass analysis of their decays to charged hadrons. Double-differential multiplicity results as a function of laboratory momentum and polar angle are presented for each particle species; these results provide vital constraints on the predicted neutrino beam flux for current and future long-baseline neutrino oscillation experiments.
