Abstract

This paper presents multiplicity measurements of charged hadrons produced in $120 GeV / c$ proton-carbon interactions. The measurements were made using data collected at the NA61/SHINE experiment during two different data-taking periods, with increased phase space coverage in the second configuration due to the addition of new subdetectors. Particle identification via $d E / d x$ was employed to obtain double-differential production multiplicities of $π^{+}$ , $π^{-}$ , $p$ , $\bar{p}$ , $K^{+}$ , and $K^{-}$ . These measurements are presented as a function of laboratory momentum in intervals of laboratory polar angle covering the range from 0 to 450 mrad. They provide crucial inputs for current and future long-baseline neutrino experiments, where they are used to estimate the initial neutrino flux.
