Strangeness Suppression and Inclusive $\phi$ and $K^*$0 Production in $K^+ P$ Interactions at 250-{GeV}/c

We present inclusive ¶ and K *0 (892) cross sections and Feynman x -spectra in K + p collisions at 250 GeV/ c . In the K + fragmentation region, x > 0.2, the ratio of ¶ to K *0 (892) is used to estimate the strangeness suppression factor λ , with the result γ =0.17 ± 0.02 (stat ± 0.01 (syst). We see no evidence for an energy dependence of λ in the CM energy range 7.8 ≤ s ≤21.7 GeV.

Energy and Quantum Number Flow in $K^+ p$ and $\pi^+ p$ Interactions at 32-{GeV}/$c$ and 70-{GeV}/$c$

The Brussels-Serpukhov-Tbilisi-Genoa-Mons-Nijmegen-CERN collaboration Azhinenko, I.V. ; Belokopytov, Yu.A. ; Vorobev, A.P. ; et al.

Inspire Record 181635 DOI 10.17182/hepdata.10881

Energy, charge and strangeness flow inK+p interactions at 32 and 70 GeV/c, and π+p interactions at 32 GeV/c are studied in terms of the angular variable λ=|x|/pT. The data ondQ/dλ anddE/dλ show only a weak indication of scale breaking between 32 and 70 GeV/c. For inclusive “non-diffractive”, inclusive “diffractive” and exclusive “non-diffractive” jets, the fraction of charge in any angular region ΔΩ away from the central region is found to be proportional to the energy fraction in the same interval. The data ondQ/dE versus λ are compatible with some versions of dual-sheet models and agree also with the LUND Monte-Carlo model. The data are also compared with\(v(\bar v)p\) interactions in BEBC. In exclusive channels the average ratiodQ/dS=0.78±0.04 is consistent, in the framework of fragmentation models, with a larger probability for the fragmentation of the\(\bar s\)-valence quark than theu-valence quark in theK+-meson.

Inclusive Production of Anti-xi+ and $\Xi^-$ in $K^+ p$ Interactions at 32-{GeV}/c

Azhinenko, I.V. ; Belokopytov, Yu.A. ; Chliapnikov, P.V. ; et al.
Nucl.Phys.B 176 (1980) 51, 1980.
Inspire Record 153556 DOI 10.17182/hepdata.11096

The inclusive production of Ξ + and Ξ − hyperons is investigated in K + p interactions at 32 GeV/ c . The production cross sections, 36.4±9 μ b for the Ξ + and 6.5±3 μ b for the Ξ − , are rising strongly with energy similarly to Λ and Λ production in K + p interactions. The Ξ + are produced preferentially in the forward direction in the c.m.s., while the Ξ − are produced dominantly backwards. The average transverse momenta 〈p T 〉 Ξ + =0.73±0.09 GeV /c and 〈 p T 〉 Ξ − =0.58±0.09 GeV/ c .

We present results on a number of non-diffractive two-body channels contributing to reactions K + p→K 0 π + p and K + p→K + π − π + p. The data come from an exposure of the Mirabelle bubble chamber to an r.f. separated K + beam of 32 GeV/ c at the Serpukhov accelerator. Total cross sections are given for the final states K ∗+ (890) p , K ∗+ (1420) p , K 0 Δ ++ (1232), K ∗+ (890) p , Δ ++ (1232), K ∗0 (1420) Δ ++ (1232), K ∗0 (1780) Δ ++ (1232) and K ∗0 (890) Δ ++ (1950) . The differential cross sections are given for all channels with sufficient statistics. The energy dependence of the total and differential cross sections is studied.

Inspire Record 121746 DOI 10.17182/hepdata.34983

The inclusive production of resonances is systematically studied in K + p interactions at 32 GeV/ c . Total production cross sections are given for three baryon resonances, five vector and three 2 + tensor mesons. We also compare the central and fragmentation components of the total production cross sections with quark model predictions.
