From a study of 1226 neutral strange particles produced in pp interactions at 69 GeV/ c in the MIRABELLE hydrogen bubble chamber, we obtain the inclusive cross sections for K S 0 , Λ / Σ 0 , Λ / Σ 0 equal to 3.43 ± 0.23, 3.44 ± 0.2 and 0.16 ± 0.03 mb, respectively. The inclusive distributions are compared with corresponding data at other energies.

We present the inclusive and semi-inclusive production of protons, π+, π−, for the full range of kinematic variables, from 7850 inelastic interactions obtained in the 4.7 m liquid-hydrogen bubble chamber Mirabelle at the Serpukhov accelerator and with an incident proton beam of 69 GeV/c. We compare the data with those at other energies, and we give the results of different phenomenological fits.

Single Particle Inclusive Spectra of Charged Particles in anti-p p Interactions at 22.4-GeV/c

The Alma Ata-Dubna-Helsinki-Kosice-Moscow-Prague collaboration Boos, E.G. ; Samoilov, V.V. ; Takibaev, Zh.S. ; et al.

Nucl.Phys.B 121 (1977) 381-392, 1977.

Inspire Record 109633 DOI 10.17182/hepdata.35465

The inclusive spectra for p p collisions at 22.4 GeV/ c are investigated. We show that the transverse momentum distributions resemble those in high-energy pp interactions and discuss the influence of annihilation processes on the p T 2 distributions. The invariant inclusive cross section for pions in the central region is found to be 28 ± 1 mb. A charge asymmetry is indicated by the y ∗ spectrum in the central region, the asymmetry parameter having the value 0.15 ± 0.01. Finally, we estimate the upper limit of the diffraction dissociation of the beam particle to be 3.68 −0.15 +0.45 mb.

Neutral Pion Production in $K^+ p$ Interactions at 32-{GeV}

The French-Soviet & CERN-Soviet collaborations Azhinenko, I.V. ; Belokopytov, Yu.A. ; Borovikov, A.A. ; et al.

Nucl.Phys.B 162 (1980) 61-78, 1980.

Inspire Record 131232 DOI 10.17182/hepdata.8076

Inclusive and semi-inclusive distributions of γ's and π 0 's in the reactions K + p → γ + X and K + p → π 0 + X at 32 GeV/ c are presented and discussed. When compared to the inclusive π − production, the π 0 cross section is found to be significantly higher in low | x | and p T regions. The data are compared with other experiments and quark fusion model predictions.

Inclusive Strange Particle Production in $\pi^+ p$ Interactions at 32-{GeV}/$c$

Azhinenko, I.V. ; Belokopytov, Yu.A. ; Borovikov, A.A. ; et al.

Nucl.Phys.B 165 (1980) 1-18, 1980.

Inspire Record 141734 DOI 10.17182/hepdata.8000

The production of K s 0 , Λ and Λ is measured in π + p interactions at 32 GeV/ c . The total inclusive cross sections are found to be 2.07±0.14, 1.00±0.10 and 0.14±0.04 mb, respectively. The energy dependence of total inclusive cross sections and inclusive distributions is discussed and a comparison is made with p, p , K + and K − induced reactions. We find that the factorization hypothesis is satisfied for the inclusive reactions π + p→ Λ X and K + p→ Λ X. Multi-strange-particle production is similar in π + p and K + p interactions at 32 GeV/ c . There is evidence for beam fragmentation in Λ production. The hierarchy of Λ inclusive cross sections in p , K + , π + and K − induced reactions at 32 GeV/ c is qualitatively explained by a quark recombination model. The cross sections for inclusive K ∗ + (892) and Σ + (1385) production in 32 GeV/ c π + p interactions are 1.07±0.57 mb and 0.19±0.08 mb, respectively.

Inclusive Production of $\rho^0$ and $\phi$ in $K^+ p$ Interactions at 32-{GeV}/c

Nucl.Phys.B 176 (1980) 303, 1980.

Inspire Record 153559 DOI 10.17182/hepdata.48999

Inclusive ϱ 0 and φ production is investigated in K + p interactions at 32 GeV/ c . Total and semi-inclusive ϱ 0 and φ cross sections, longitudinal and transverse momentum distributions, including 〈 P T versus x dependence are presented. No evidence for a sea-gull effect is observed. Comparison with quark models strongly suggests the possibility that a large fraction of the ϱ 0 and vector mesons are produced as fragmentation products of the incident particles. Study of uncorrelated π + π − pairs in the ϱ 0 mass range provides possible indirect evidence for the existence of diquarks in the proton.

Total and semi-inclusive cross sections, longitudinal and transverse momentum distributions and spin density matrix elements of theK*+(892) andK*0(892) produced in the inclusive reactionsK+p→K*+(892)+X andK+p→K*0(892)+X at 32 GeV/c are studied in detail. The inclusive spectra of theK*(892) and their decay products are compared with pion and neutral kaon production. TheK*+(892) andK*+(892) are dominantly produced by kaon fragmentation processes. The dependence of average transverse momentum <pT> vs.x for resonances has been investigated for the first time.
