Abstract

Measurements of K-S(0) meson production via its pi+pi- decay mode in inelastic p+p interactions at incident projectile momenta of 31, 40 and 80 GeV/c (root 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))x10(-2) at 31 GeV/c, (7.61 +/- 0.13(stat)+/- 0.31(sys))x10(-2) at 40 GeV/c and (11.58 +/- 0.12(stat)+/- 0.37(sys))x10(-2) at 80 GeV/c. The results on K-S(0) production are compared with model calculations (Epos1.99, SMASH 2.0 and PHSD) as well as with published data from other experiments.
