A systematic study of p p and p d reactions producing strange particles between 1.09 and 3.45 GeV/ c has been completed. Reaction and resonance cross-section data are presented at 11 p p and 13 p d momentum settings. Evidence for a broad shoulder in the K K 3π final state near 1.8 GeV/ c is presented and contrasted to previously published work on a portion of the final data sample. No evidence for a p n → K 0 K − ω effect near 1.3 GeV/ c is found, ruling out an association of K K ω effects with the nearby isospin one enhancement in the total cross section. Finally, we find no evidence for a p p → K K ω enhancement near 1.8 GeV/ c .

DIFFERENCES BETWEEN ANTI-P P AND P P INTERACTIONS AT 8.8-GeV/c AND THEIR RELATIONSHIP TO ANTI-P P ANNIHILATIONS

Booth, C.n. ; Ansorge, R.e. ; Carter, J.r. ; et al.
Phys.Rev.D 27 (1983) 2018, 1983.
Inspire Record 194364 DOI 10.17182/hepdata.23838

We report on an experiment in which the SLAC 40-in. hybrid facility was exposed to an 8.8-GeV/c antiproton beam. Using external detectors we have identified a large fraction of nonannihilation events and thus obtained a clean sample of annihilation data. Using proton interactions taken in the same detector at the same energy we have made a detailed study of (p¯p−pp) differences and explored their relationship to p¯p annihilations.

Results from E735 at the tevatron proton - anti-proton collider with s**(1/2) = 1.8-TeV

The E735 collaboration Lindsey, Clark S. ; Alexopoulos, T. ; Allen, C. ; et al.
Nucl.Phys.A 544 (1992) 343-356, 1992.
Inspire Record 322633 DOI 10.17182/hepdata.43062

Experiment E735 searched for evidence of the transition to quark-gluon plasma in p p collisions at √ s = 1.8 TeV. Using data from a high statistics run in 1988–1989, results are presented on multiplicity distributions, hyperon and phi production, and Bose-Einstein correlations. Some data were also taken at lower collision energies and results will be compared to previous experiments.

Study of anti-p p ---> lambda(sigma0) anything at 5.7 gev/c

Ganguli, S.N. ; Sadoulet, B. ;
Nucl.Phys.B 53 (1973) 458-472, 1973.
Inspire Record 84214 DOI 10.17182/hepdata.32591

We present a study of the incclusive reaction p p → Λ/Σ 0 + anything at 5.7 GeV/ c based on 9544 events. The main experimental feature is a flattening of the momentum-transfer distribution with the increasing missing mass. We attempt to interpret the results in the framework of the triple-Regge limit. The effective trajectory is shown to be in good agreement, within theoretical uncertainties, with what is expected from K or K ∗ – K ∗∗ exchanges.

Hyperon Production at 200-{GeV} and 900-{GeV} Center-of-mass Energy

The UA5 collaboration Ansorge, R.E. ; Asman, B. ; Burow, L. ; et al.
Nucl.Phys.B 328 (1989) 36-58, 1989.
Inspire Record 277298 DOI 10.17182/hepdata.33174

The production of Λ 's and Ξ − 's in proton-antiproton collisions at 200 and 900 GeV c.m. energy has been studied using decays observed in the UA5 streamer chambers. The results are compared to previously published 546 GeV data, to results from other experiments, and to four theoretical models. The Λ yield per inelastic event is estimated to be 0.42±0.11 at 200 GeV and 0.66±0.14 at 900 GeV. We find a mean number of Ξ − 's per inelastic collision of 0.03 −0.02 +0.04 at 200 GeV and 0.06 −0.03 +0.05 at 900 GeV. The average transverse momentum of Λ's in the rapidity region | y |⩽2 is found to be 0.80 −0.14 +0.20 GeV/ c at 200 GeV and 0.74±0.09 GeV/ c at 900 GeV. The average transverse momentum of Ξ − 's in the rapidity region | y |⩽3 is estimated to be 0.8 −0.2 +0.4 GeV/ c at 200 GeV and 0.7 −0.1 +0.2 GeV/ c at 900 GeV which is lower than the unexpectedly high value of 1.1±0.2 GeV/ c measured at 546 GeV. The ratio of Ξ − production to Λ production in the region | y |⩽2, p t >1 GeV/ c is 0.07 −0.04 +0.08 at 900 GeV. This value is consistent with the ratio found in e + e − collisions and lower energy pp collisions but lower than the value obtained at 546 GeV. The average particle composition of events at 200 and 900 GeV, estimated using UA5 data, is presented.

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.
