Abstract

AbstractThe yields of

$$K^0_S$$

K S 0 mesons have been measured in inelastic p+p interactions at incident projectile momenta of 31, 40 and 80

$$\text {Ge}\hspace{-1.00006pt}\text {V}\!/\!c$$

Ge V / c (

$$\sqrt{s_{NN}}=7.7, 8.8$$

s NN = 7.7 , 8.8 and 12.3

$$\text {Ge}\hspace{-1.00006pt}\text {V}$$

Ge V , respectively). The data were recorded by the NA61

$$/$$

/ SHINE spectrometer at the CERN Super Proton Synchrotron and the

$$K^0_S$$

K S 0 mesons identified via their decays into

$$\pi ^{+} \pi ^{-}$$

π + π - pairs. Double-differential distributions are presented as function of transverse momentum and rapidity. The mean multiplicities of

$$K^0_S$$

K S 0 mesons were determined to be

$$(5.95 \pm 0.19 (stat) \pm 0.30 (sys)) \times 10^{-2}$$

( 5.95 ± 0.19 ( s t a t ) ± 0.30 ( s y s ) ) × 10 - 2 at 31

$$\text {Ge}\hspace{-1.00006pt}\text {V}\!/\!c$$

Ge V / c ,

$$(7.61 \pm 0.13 (stat) \pm 0.43 (sys)) \times 10^{-2}$$

( 7.61 ± 0.13 ( s t a t ) ± 0.43 ( s y s ) ) × 10 - 2 at 40

$$\text {Ge}\hspace{-1.00006pt}\text {V}\!/\!c$$

Ge V / c and

$$(11.58 \pm 0.12 (stat) \pm 0.55 (sys)) \times 10^{-2}$$

( 11.58 ± 0.12 ( s t a t ) ± 0.55 ( s y s ) ) × 10 - 2 at 80

$$\text {Ge}\hspace{-1.00006pt}\text {V}\!/\!c$$

Ge V / c . The results on

$$K^{0}_{S}$$

K S 0 production are compared with the production of charged kaons in corresponding reactions and with model calculations (Epos1.99, SMASH 2.0 and PHSD) as well as with published data from other experiments.
