Cross-sections for deuterium, tritium, and helium production in p p collisions at s = 1.8-TeV

Alexopoulos, T. ; Anderson, E.W. ; Biswas, N.N. ; et al.
Phys.Rev.D 62 (2000) 072004, 2000.
Inspire Record 536253 DOI 10.17182/hepdata.22220

We present the results of a search for the production of light elements in p¯p collisions at the Fermilab Tevatron collider. Momentum, time of flight, and dE/dx measurements are used to distinguish nuclei from elementary particles. A production ratio for deuterium to hydrogen is calculated and compared to the primordial value of the big bang model. Some evidence for tritium is found and none for helium isotopes.

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.

Diffractive Dissociation of the Beam Particle in anti-p p Interactions at 32.1-GeV/c

Phys.Lett.B 59 (1975) 409, 1975.
Inspire Record 98777 DOI 10.17182/hepdata.27764

We report the results of a study of the reaction p p → p + x at 32.1 GeV c , where the recoiling proton has a small laboratory momentum. The reaction is studied in the 4.5 m Mirabelle bubble chamber at Serpukhov. We compare the diffractive dissociation of the incident antiproton to other incident particles.

New results on the inclusive and semi-inclusive production of π + mesons and protons in the whole phase space are given for about 2.2 · 10 4 inelastic p p interactions at 22.4 GeV/ c . A method of statistical separation for spectra of particles of the same charge which are produced in CP -symmetrical reactions is discussed in detail. Experimental data are compared with quark-parton model predictions.

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.

The s Dependence of Proton Fragmentation by Hadrons. 2. Incident Lab Momenta 30-GeV/c - 250-GeV/c

Weisberg, H. ; Beier, E. ; Brody, H. ; et al.
Phys.Rev.D 17 (1978) 2875, 1978.
Inspire Record 122402 DOI 10.17182/hepdata.24404

Measurements of inclusive scattering in the target-fragmentation region are extended to higher incident energy. The combined data set shows departures from an approach to the asymptotic scaling limit as A+Bs−12 that are significant even at the highest energies. When these departures are taken into account, the data approach a limit that is consistent with equal cross sections induced by particles and antiparticles and with Pomeron factorization. The corrections to A+Bs−12 are so large that detailed tests of Mueller-Regge relationships are not conclusive.

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.
