“…For the Λ production on π beams the disagreement between the theoretical calculations for the two different values of α SJ = 0.5, 0.9, are within the experimental uncertainty. The experimental data on x F spectra of secondary Λ in π ± p collisions at 147 GeV/c [20] and 250 GeV/c [21,22], together with QGMS description. The full line corresponds to calculations with α SJ = 0.5, while the dashed line corresponds to α SJ = 0.9.…”

“…As it was shown in [8,9] the data at comparatively low energies ( √ s ∼ 15÷40 GeV) can be described with the values α SJ = 0.5 and ε = 0.05 (see [8]), or α SJ = 0.9 and ε = 0.024 [9]. The inclusive spectra of secondary Λ produced in πp collisions at energies 147 GeV/c [20] and 250 GeV/c [21,22] are shown in Fig. 1 together with the curves calculated in the QGSM at 250 GeV for both values of α SJ .…”

“…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

“…The production of V 0 particles has been studied by numerous experiments with different beams (π, K, p, n, Σ − ) on different targets, covering a momentum range of 4-400 GeV/c (see [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20] and refs. therein).…”

Inclusive differential cross sections dσ pA /dx F and dσ pA /dp 2 t for the production of K 0 S , Λ, andΛ particles are measured at HERA in proton-induced reactions on C, Al, Ti, and W targets. The incident beam energy is 920 GeV, corresponding to √ s = 41.6 GeV in the proton-nucleon system. The ratios of differential cross sections dσ pA (K 0 S )/dσ pA (Λ) and dσ pA (Λ)/dσ pA (Λ) are measured to be 6.2 ± 0.5 and 0.66 ± 0.07, respectively, for x F ≈ −0.06. No significant dependence upon the target material is observed. Within errors, the slopes of the transverse momentum distributions dσ pA /dp 2 t also show no significant dependence upon the target material. The dependence of the extrapolated total cross sections σ pA on the atomic mass A of the target material is discussed, and the deduced cross sections per nucleon σ pN are compared with results obtained at other energies.
