Negative Hyperon Production in High-Energy Proton Interactions

Hungerbuhler, V. ; Majka, R. ; Marx, J.N. ; et al.
Phys.Rev.D 12 (1975) 1203-1210, 1975.
Inspire Record 104138 DOI 10.17182/hepdata.4668

Momentum spectra for forward Σ− and Ξ− production by protons on beryllium are presented. Σ− production data for two primary proton momenta are compared to test scaling of the invariant cross section. In addition, the observed single-particle momentum distributions are compared with single-particle spectra from other inclusive reactions initiated by protons.

New Measurements of Polarization and Differential Cross-Sections in K+ p Elastic Scattering in the 1.7-GeV/c-3-GeV/c Range

Patton, R. ; Barletta, W.A. ; Ehrlich, R.D. ; et al.
Phys.Rev.Lett. 34 (1975) 975-978, 1975.
Inspire Record 102699 DOI 10.17182/hepdata.21222

We have measured the polarization parameter and differential cross sections in K+p elastic scattering from a polarized target from small |t| and small |u| at five momentum points: 1.7, 2.1, 2.4, 2.7, and 3.0 GeV/c. The polarized-proton target was butanol cooled at 0.5° by a He3-He4 refrigerator; a combination of multiwire proportional chambers and scintillation counters detected the scattered particles. The results for small |u| are discussed in the context of pure Regge-pole models with exchange-degenerate Λ trajectories.

Search for Narrow Resonances in e+ e- Annihilation in the Mass Region 3.2-GeV to 5.9-GeV

Boyarski, A. ; Breidenbach, Martin ; Bulos, F. ; et al.
Phys.Rev.Lett. 34 (1975) 762, 1975.
Inspire Record 100594 DOI 10.17182/hepdata.21228

We have searched the mass region 3.2 to 5.9 GeV for evidence of narrow resonances in e+e−→hadrons. We find no evidence for any such resonances other than the ψ(3695) in this region with a sensitivity ranging from about 12 to 45% of the integrated cross section of the ψ(3695). The more stringent bounds apply to resonances of a few MeV width, while the looser bounds apply to resonances of up to 20 MeV width.

rivet Analysis
Total Cross-Section for Hadron Production by electron-Positron Annihilation Between 2.4-GeV and 5.0-GeV Center-Of-Mass Energy

Augustin, J.E. ; Boyarski, A. ; Breidenbach, Martin ; et al.
Phys.Rev.Lett. 34 (1975) 764, 1975.
Inspire Record 100592 DOI 10.17182/hepdata.21227

The total cross section for hadron production by e+e− annihilation has been measured at center-of-mass energies between 2.4 and 5.0 GeV. Aside from the very narrow resonances ψ(3105) and ψ(3695), the cross section varies between 32 and 17 nb over this region with structure in the vicinity of 4.1 GeV.

Polarized Photon Asymmetries in K+ Photoproduction at 16-GeV

Quinn, D.J. ; Rutherfoord, J.P. ; Shupe, M.A. ; et al.
Phys.Rev.Lett. 34 (1975) 543, 1975.
Inspire Record 100595 DOI 10.17182/hepdata.21241

Using a 16-GeV linearly polarized photon beam, we have measured asymmetries in the process γN→K+(Λ+Σ) from hydrogen and deuterium, for square of four-momentum transfer, t, between -0.01 and -0.8 (GeV/c)2. The data show that for −t≳0.1 (GeV/c)2, the cross sections for γp→K+Λ, γp→K+Σ0, and γn→K+Σ− are strongly dominated by natural-parity exchange, as is the case in single-pion photoproduction.
