Banerjee, S. ; Ganguli, S.N. ; Malhotra, P.K. ; et al.

Nucl.Phys.B 150 (1979) 119-140, 1979.

Inspire Record 131498 DOI 10.17182/hepdata.34804

We present a study of the inclusive reactions p p → K S 0 X, ΛX and Λ X at 3.6 GeV/ c based on 35.4 events/μb. The cross sections are presented in terms of the Feynman variable, rapidity and the transverse momentum. The absolute value of the Λ polarization is found to increase with increasing p T of Λ. A comparison of the inclusive productions of K S 0 in p p and e + e − is presented.

Results are presented on the inclusive reactions p p → K 0 X , p p → Λ X and p p → Λ X at an incident antiproton momentum of 12 GeV/ c in BEBC. The cross sections are studied as functions of the Feynman scaling variable x , the rapidity, the transverse momentum of the V 0 and the missing mass squared. The dependence of the Λ and Λ polarization on x are also studied. Comparisons with proton-proton data at 12 GeV/ c are also made. Finally, events with two detected V 0 are analyzed in order to study correlations arising from the production of two strange neutral particles.

Comparison of Neutral Particle Production in 100-GeV/c anti-p p and p p Interactions.

Ward, D.R. ; Ansorge, R.E. ; Bust, C.P. ; et al.

We derive cross-sections for the inclusive productiion in p̄p interactions at 100 GeV /c of π 0 , K S 0 and Λ 0 Λ 0 of 91.5±5.7 mb, 5.2±0.4 mb and 4.8±0.4 mb respectively, which are all higher than pp cross-sections at energy. We find indications that these differences can be attributed to “annihilation” processes.

Neutral Particle Production in 100-GeV/c $\bar{p}p$ Interactions

Raja, R. ; Moore, Craig D. ; Voyvodic, L. ; et al.

Phys.Rev.D 15 (1977) 627, 1977.

Inspire Record 110399 DOI 10.17182/hepdata.24539

We have investigated the inclusive production of γ, KS0, Λ0, and Λ¯0 in 100-GeV/c p¯p interactions in the 30-in. hydrogen bubble chamber at Fermilab. We present various inclusive distributions and compare them with corresponding distributions in 100-GeV/c pp interactions and lower-energy p¯p interactions. We find some evidence for Σ(1385) production but none for K*(890) production. We find evidence for a nonzero Λ0 polarization of -0.45 ± 0.21.

Inspire Record 179888 DOI 10.17182/hepdata.2239

Absolute inclusive cross sections for$\bar pp$ interactions at 7.3 GeV/c are given. The data cover prong cross sections,V0, γ production and inclusive charged particle (p/π) production. Separation has been made into annihilation and non-annihilation components. Inclusive π+, π− production in the processes of$\bar pp$ annihilation and non-annihilation are compared with simple quark models.

Inspire Record 171896 DOI 10.17182/hepdata.2142

The inclusiveKn, ¶,and$\bar \Lambda$ production has been studied in a$\bar pp$ experiment performed in the Mirabelle bubble chamber at an incident beam momentum of 32.1 GeV/c. Total, topological and differential cross sections are presented and compared with those obtained at other energies. The invariant structure functions have been parametrised in the fragmentation region by a power law and are consistent with the expectations based on quark counting rules.

CROSS-SECTIONS FOR EXCLUSIVE CHANNELS IN anti-p p REACTIONS AT 12-GeV/c

Z.Phys.C 11 (1982) 273, 1982.

Inspire Record 167028 DOI 10.17182/hepdata.16434

The data obtained in an exposure of BEBC to an r.f. separated beam of antiprotons at 12 GeV/c are used to derive exclusive cross sections for reactions having one or more neutral strange particles in the final state. Particular attention is given to the estimation of the background. An upper limit of the cross section for the inclusive production of the charmed mesonD* is also given.
