“…This was estimated by an alternative procedure based on a parametrisation of published rapidity distributions. In an iterative procedure a symmetric polynomial of 4 th order [22] was fitted to the (1/ n )(dn/dz) distributions obtained by five bubble-chamber experiments [23][24][25][26][27] and the NA61/SHINE data, where z stands for y/y beam . First, the fit included only the five bubble-chamber datasets.…”

“…15 to results from five bubble-chamber experiments which measured p+p interactions at beam momenta close to 158 GeV/c. The experiments published data for the backward hemisphere, however, with rather small statistics [23][24][25][26][27] and correspondingly large uncertainties. In order to account for the difference in beam momentum the spectra are shown in terms of the scaled rapidity z = y/y beam for six bins in rapidity y.…”

Inclusive production of -hyperons was measured with the large acceptance NA61/SHINE spectrometer at the CERN SPS in inelastic p+p interactions at beam momentum of 158 GeV/c. Spectra of transverse momentum and transverse mass as well as distributions of rapidity and x F are presented. The mean multiplicity was estimated to be 0.120 ± 0.006 (stat.) ±0.010 (sys.). The results are compared with previous measurements and predictions of the Epos, Urqmd and Fritiof models.

“…Experimental data on strange particle production in protonproton and proton-carbon interactions in the region below few tens of GeV/c incident momentum are scarce [1][2][3][4]. There are at least two reasons why the knowledge of yields of strange mesons and baryons are of considerable interest at the beam momentum of 31 GeV/c.…”

Spectra of K 0S mesons and hyperons were measured in p + C interactions at 31 GeV/c with the large acceptance NA61/SHINE spectrometer at the CERN SPS. The data were collected with an isotropic graphite target with a thickness of 4% of a nuclear interaction length. Interaction cross sections, charged pion spectra, and charged kaon spectra were previously measured using the same data set. Results on K 0 S and production in p + C interactions serve as a reference for the understanding of the enhancement of strangeness production in nucleus-nucleus collisions. Moreover, they provide important input for the improvement of neutrino flux predictions for the T2K long baseline neutrino oscillation experiment in Japan. Inclusive production cross N.

The results are compared with predictions of several hadron production models. The K 0 S mean multiplicity in production processes n K 0 S and the inclusive cross section for K 0 S production σ K 0 S were measured and amount to 0.127 ± 0.005 (stat) ± 0.022 (sys) and 29.0 ± 1.6 (stat) ± 5.0 (sys) mb, respectively.

The problem of pinning down the critical point of strongly interacting matter still puzzles the community. One of the answers suspected to emerge in the near future will surely come from NA61/SHINE -a fixed-target experiment aiming to discover the critical point as well as to study the properties of the onset of deconfinement. This goal will be pursued by obtaining precise data on hadron production in proton-proton, proton-nucleus and nucleus-nucleus interactions in a wide range of system size and collision energy. This contribution presents new results on inclusive spectra of identified hadrons and on fluctuations in inelastic p+p and Be+Be interactions at the SPS energies. These are compared with the world data, in particular with the corresponding measurements of NA49 for central Pb+Pb collisions as well as with some model predictions.
