Abstract

This paper presents multiplicity measurements of $K_{S}^{0}$, $\Lambda$, and $\bar{\Lambda}$ produced in $120$ GeV/$c$ $p+C$ interactions. The measurements were made using data collected at the NA61/SHINE experiment during two different periods. Decays of these neutral hadrons impact the measured $\pi^{+}$, $\pi^{-}$, $K^{+}$, and $K^{-}$ multiplicities in the $120$ GeV/$c$ $p+C$ reaction, which are crucial inputs for long-baseline neutrino experiment predictions of neutrino beam flux. The double-differential multiplicities presented here will be used to more precisely measure charged-hadron multiplicities in this reaction, and to reweight neutral hadron production in neutrino beam Monte Carlo simulations.
