KS0 production in p+p interactions measured by NA61/SHINE

Abstract

The NA61/SHINE collaboration measured the production of [Formula: see text] in [Formula: see text] interactions at two beam momenta: 80 and 158[Formula: see text]GeV/c. The [Formula: see text] decay of [Formula: see text] (branching ratio of 69.2%) was measured via the invariant mass method. The rapidity and transverse momentum distributions of [Formula: see text] are presented and compared to transport model predictions. The measured mean multiplicities of [Formula: see text] mesons equal to [Formula: see text] (80[Formula: see text]GeV/c) and [Formula: see text] (158[Formula: see text]GeV/c) are compared with the available data in the energy range [Formula: see text]–32[Formula: see text]GeV.
