摘要

Measurements of K_S^0 meson production via its π^+π^- decay mode in inelastic p+p interactions at incident projectile momenta of 31, 40 and 80 GeV/c (√(s_NN)=7.7, 8.8 and 12.3 GeV, respectively) are presented. The data were recorded by the NA61/SHINE spectrometer at the CERN Super Proton Synchrotron. Double-differential distributions were obtained in transverse momentum and rapidity. The mean multiplicities of K_S^0 mesons were determined to be (5.95 ± 0.19 (stat) ± 0.22 (sys)) × 10^-2 at 31 GeV/c, (7.61 ± 0.13 (stat) ± 0.31 (sys)) × 10^-2 at 40 GeV/c and (11.58 ± 0.12 (stat) ± 0.37 (sys)) × 10^-2 at 80 GeV/c. The results on K^0_S production are compared with model calculations (Epos1.99, SMASH 2.0 and PHSD) as well as with published data from other experiments.
