Boson States in the Reaction pi- p --> pi- pi- pi+ p with Leading pi+ Meson at 25-GeV/c

The Serpukhov-CERN collaboration Antipov, Yu.M. ; Busnello, R. ; Damgaard, G. ; et al.
Nucl.Phys.B 119 (1977) 45-59, 1977.
Inspire Record 109772 DOI 10.17182/hepdata.35516

The reaction π − + p → π − + π − + π + + p at 25 GeV/ c was studied in the mass region M 3 π ⩾ 1.8 GeV with leading π + . The mass spectrum of the π + π − system shows peaks corresponding to the ϱ 0 , f and g 0 resonances and an enhancement around 1.9 GeV. Evidence is presented for a J P = 3 + s-wave g 0 π − state (A 4 ) similar to the ϱ 0 π − (A 1 ) and fπ − (A 3 ) threshold enhancements.

Anti-Proton-Proton Annihilation Into pi+ pi- and K+ K- at 6.2-GeV/c

Buran, T. ; Eide, A. ; Helgaker, P. ; et al.
Nucl.Phys.B 116 (1976) 51-64, 1976.
Inspire Record 110027 DOI 10.17182/hepdata.35565

The angular distributions for the two annihilation channels p ̄ p →π + π − and p ̄ p → K + K − have been measured at 6.2 GeV/ c . The two-pion channel shows peripheral peaks for π + and π − going forward, and the two-kaon channel shows a peripheral peak for the K − going forward. The results have been compared with the line-reversed elastic backward scattering reactions and also with a constituent interchange model.

A Measurement of the Polarization Parameter in Backward pi- p Elastic Scattering at 3.5-GeV/c

The CERN-Trieste collaboration Birsa, R. ; Bradamante, F. ; Conetti, S. ; et al.
Nucl.Phys.B 117 (1976) 77-94, 1976.
Inspire Record 110105 DOI 10.17182/hepdata.35603

The polarization parameter has been measured for π − p elastic scattering in the backward region at 3.5 GeV/ c incident momentum. The experimental set-up consisted of a polarized target in a spectrometer magnet, hodoscopes and wire spark chambers. Data are presented for the range −0.95< u ⩽−0.19 GeV 2 . An isospin analysis has been carried out to separate the I u = 1 2 and I u = 3 2 contributions.

Neutron Fragmentation and Inclusive Charge Exchange in p d and pi+ d Interactions at 195-GeV/c

Eisenberg, Y. ; Haber, B. ; Hochman, D. ; et al.
Phys.Rev.Lett. 38 (1977) 108, 1977.
Inspire Record 109610 DOI 10.17182/hepdata.21024

An excess of negative particles and depletion of positive particles in the backward hemisphere (c.m. system) is observed in π+ and p interactions on neutron target. dσ−dy is compared with pp interactions and the difference is related to the slow-proton spectrum produced in the pn interactions. A neutron fragmentation component is observed and the inclusive charge-exchange probability at the nucleon vertex is found to be about 0.4.

Observation of Neutron Neutron Interactions with Double Diffraction Dissociation at the ISR

Mantovani, G.C. ; Cavalli-Sforza, M. ; Conta, C. ; et al.
Phys.Lett.B 65 (1976) 401-404, 1976.
Inspire Record 110581 DOI 10.17182/hepdata.27598

Neutron-neutron interactions have been observed at the CERN ISR with deutron colliding beams. The double - diffraction dissociation process →(p π p − )( pπ − ) has been measured with the Split Field Magnet at √ s = 26 GeV detecting all final state particles, including the two spectator protons. Mass and t distributions are presented and compared with corresponding spectra observed in single neutron diffraction in the same energy range with supporting evidence for factorization. The cross-section of the process is 11.5±2.8 μ b and can be directly related to the corresponding value for double diffraction dissociation of protons in the same energy range.

Phys.Lett.B 66 (1977) 395-400, 1977.
Inspire Record 110272 DOI 10.17182/hepdata.27583

Using the solenoidal magnetic detector PLUTO, we have measured the total cross section for e + e − annihilation into hadrons. Results are presented for center of mass energies between 3.6 and 4.8 GeV, and in the regions of the J ψ (3.1) and ψ(3.7) resonances. We also present results for the 2 prong cross section in the energy range 3.6 to 4.8 GeV.

Hyperon-anti-Hyperon Production in anti-p p Interactions at 3.6-GeV/c Leading to 3 Or More Particles in the Final State

Inspire Record 110545 DOI 10.17182/hepdata.35525

Results are presented on the properties of the p p interactions at 3.6 GeV/ c leading to a hyperon or an antihyperon in final states with ⩾3 particles from an experiment of 35 eV/μb sensitivity. Results of amultidimensional mass fit to each final state are given along with the cross sections, differential cross sections and polarization, where possible, for the hypercharge exchange reactions p p → Λ Y ∗ (1385), Λ Y ∗ (1520), Σ Y ∗ (1385) and Σ Y ∗ (1520) .

The Real Part of the Forward Proton Proton Scattering Amplitude Measured at the CERN Intersecting Storage Rings

Amaldi, U. ; Cocconi, G. ; Diddens, A.N. ; et al.
Phys.Lett.B 66 (1977) 390-394, 1977.
Inspire Record 110800 DOI 10.17182/hepdata.27584

The real part of the proton proton elastic scattering amplitude has been determined from its interference with the Coulomb amplitude at total centre-of-mass energies up to 62 GeV. The observed steady increase of ϱ with energy indicates that the total proton proton cross section continues to increase well beyond this energy.
