Query: $K^{0}_{S}$ meson production in inelastic $\textit{p+p}$ interactions at
  158 GeV/c beam momentum measured by NA61/SHINE at the CERN SPS   The production of $K^{0}_{S}$ mesons in inelastic $\textit{p+p}$ collisions
at beam momentum 158 GeV/c ($\sqrt{s_{NN}}=17.3$ GeV) was measured with the
NA61/SHINE spectrometer at the CERN Super Proton Synchrotron.
Double-differential distributions were obtained in transverse momentum and
rapidity. The mean multiplicity of $K^{0}_{S}$ was determined to be $0.162 \pm
0.001 (stat.) \pm 0.011 (sys.)$. The results on $K^{0}_{S}$ production are
compared with model predictions (EPOS 1.99, SMASH 2.0, PHSD and UrQMD 3.4
models) as well as with published world data.
