Measurements of K S 0 , Λ , and Λ ¯ production in 120     GeV / c p + C interactions

This paper presents multiplicity measurements of $K^0_S$, Λ, and $\bar{Λ}$ produced in 120 GeV/c proton-carbon 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 π+, π-, p and $\...

Zusammenfassung:This paper presents multiplicity measurements of $K^0_S$, Λ, and $\bar{Λ}$ produced in 120 GeV/c proton-carbon 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 π+, π-, p and $\bar{p}$ multiplicities in the 120 GeV/c proton-carbon 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.
