“…In most cases Phojet as well as several Phythia tunes are well below the data -by factors of two to almost five -and more so at high p T and for the heavier particles (Λ, Ξ). The ratio of Λ to K 0 S , shown in Figure 3, agrees very well with the STAR data at 200 GeV [15] but is significantly below the ratio measured by UA1 [16] and CDF [17]. This discrepancy merits further investigation; it could be due to differences between the experiments in the acceptance, triggers, or correction for feed-down from weak decays.…”

It includes the ( + )/2K 0 S ratio in pp collisions at 200 GeV measured by STAR [28], and the ratios in pp collisions at 630 GeV and 1800 GeV computed with the ( + ) and K 0 S spectra published by CDF [41] and UA1 [42]. UA1 and CDF Collaborations provide inclusive spectra whereas the ALICE and STAR ones are feed- [28,32] and the ISR parameterization [33].…”

The production of mesons containing strange quarks (K 0 S , φ) and both singly and doubly strange baryons ( , , and − + + ) are measured at mid-rapidity in pp collisions at √ s = 0.9 TeV with the ALICE experiment at the LHC. The results are obtained from the analysis of about 250 k minimum bias events recorded in 2009. Measurements of yields (dN/dy) and transverse momentum spectra at mid-rapidity for inelastic pp collisions are presented. For mesons, we report yields ( dN/dy ) of 0.184 ± 0.002(stat.) ± 0.006(syst.) for K 0 S and 0.021 ± 0.004(stat.) ± 0.003(syst.) for φ. For baryons, we find dN/dy = 0.048 ± 0.001(stat.) ± 0.004(syst.) for , 0.047 ± 0.002(stat.) ± 0.005(syst.) for and 0.0101 ± 0.0020(stat.) ± 0.0009(syst.) for − + + . The results are also compared with predictions for identified particle spectra from QCD-inspired models and provide a baseline for comparisons with both future pp measurements at higher energies and heavy-ion collisions.

“…7 for the three target materials. The STAR measurements [26] in pp interactions at √ s = 200 GeV and UA1 [25] in pp interactions at √ s = 630 GeV are also shown. The ratio shows no appreciable dependence on center-of-mass energy, atomic number or the type of colliding particles over the measured range.…”

“…Numerous studies have been made (see [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], and references therein) including fixed-target experiments at Center-of-Mass (CM) energies up to 40 GeV, mainly with bubble chambers, as well as at CERN's Intersecting Storage Ring in the 1970s and early 1980s (see [21][22][23][24]) and later at the SPS Collider [25]. More recently, studies of strangeness production at a CM energy of 200 GeV in both proton-proton and deuterongold collisions at RHIC have been published [26,27].…”

Inclusive doubly differential cross sections d 2 σ pA /dx F dp 2 T as a function of Feynman-x (x F ) and transverse momentum (p T ) for the production of K 0 S , Λ andΛ in proton-nucleus interactions at 920 GeV are presented. The measurements were performed by HERA-B in the negative x F range (−0.12 < x F < 0.0) and for transverse momenta up to p T = 1.6 GeV/c. Results for three target materials: carbon, titanium and tungsten are given. The ratios of production cross sections are presented and discussed. The Cronin effect is clearly observed for all three V 0 species. The atomic number dependence is parameterized as σ pA = σ pN · A α where σ pN is the proton-nucleon cross section. The measured values of α are all near one. The results are compared with EPOS 1.67 and PYTHIA 6.3. EPOS reproduces the data to within ≈ 20% except at very low transverse momentum. a
