Polarized Target Asymmetry in $\pi^+$ Photoproduction Between 0.3-GeV and 1.0-GeV at 130°

Feller, P. ; Fukushima, M. ; Horikawa, N. ; et al.
Nucl.Phys.B 102 (1976) 207, 1976.
Inspire Record 90055 DOI 10.17182/hepdata.36079

The polarized target asymmetry for γ + p → π + + n was measured at c.m. angles around 130° for the energy range between 0.3 and 1.0 GeV. A magnetic spectrometer system was used to detect π + mesons from the polarized butanol target. The data show two prominent positive peaks at 0.4 and 0.8 GeV and a deep minimum at 0.6 GeV. These features are well reproduced by the phenomenological analysis made by us.

Blieden, H.R. ; Finocchiaro, G. ; Goldhaber, A.S. ; et al.
Phys.Rev.D 11 (1975) 14, 1975.
Inspire Record 90186 DOI 10.17182/hepdata.4892

Targets made of C, Al, Cu, Pb, and U were exposed to π+, π−, and proton beams of 9.92 and 19.85 GeV/c (for p-Pb only) at the Brookhaven AGS. A magnetic spectrometer with spark chambers was used to detect elastically scattered particles in the Coulomb-nuclear interference region (5-35 mrad). Differential cross sections are presented and compared with an optical model, taking full account of multiple scattering in the target.

Total cross sections of π± and K± on protons and deuterons have been measured at 50, 100, 150, and 200 GeV/c. All of the cross sections rise with increasing momentum.

Muon-Deuterium Deep Inelastic Scattering

Kim, I.J. ; Entenberg, A. ; Jostlein, H. ; et al.
Phys.Rev.Lett. 33 (1974) 551, 1974.
Inspire Record 1427 DOI 10.17182/hepdata.21238

We have measured deep inelastic muon-deuteron scattering in the range 0.4<Q2<3.4 and 1.6<ν<5.6 GeV. We have extracted the neutron structure function and find that νW2n differs significantly from νW2p, as also found in e−d scattering. To compare μ−d and e−d scattering we form the ratio r(Q2)=(νW2)μd(νW2)ed=N(1+Q2Λ2)−2 and find N=0.925±0.038 and 1Λ2=−0.019±0.016.

Total Cross-Sections of p and anti-p on Protons and Deuterons Between 50-GeV/c and 200-GeV/c

Carroll, A.S. ; Chiang, I.-H. ; Kycia, T.F. ; et al.
Phys.Rev.Lett. 33 (1974) 928, 1974.
Inspire Record 90202 DOI 10.17182/hepdata.21291

Proton and antiproton total cross sections on protons and deuterons have been measured at 50, 100, 150, and 200 GeV/c. The proton cross sections rise with increasing momentum. Antiproton cross sections fall with increasing momentum, but the rate of fall decreases between 50 and 150 GeV/c, and from 150 to 200 GeV/c there is little change in cross section.

A Test of the Optical Theorem

Inspire Record 90454 DOI 10.17182/hepdata.27919

Forward differential cross sections for π − p elastic scattering at 1.0, 1.5 and 2.0 GeV/ c show that the square of the imaginary parts of the nuclear scattering agrees with the optical theorem prediction within ±3%, when averaged over the three momenta.

The final states\(\bar p\)pω and\(\Delta ^{ ++ } \bar \Delta ^{ -- } \pi ^0 \), produced in the reaction\(\bar p\)p →\(\bar p\)pπ+π−π0 (6435 events) at 5.7 GeV/c, are studied. Cross-sections are presented, and general features of the resonances produced are investigated. Spin alignment of the ω’s, reported earlier, is studied. An enhancement is observed in the ωp (ω\(\bar p\)) mass plot of mass (1810±15) MeV and width (87 ± 20) MeV.

New Data on the Reaction K- p ---> Lambda pi0 from 1.934-GeV/c to 2.516-GeV/c and Partial Wave Analysis for This Reaction, Between 2070-MeV and 2436-MeV CMS Energy

Nucl.Phys.B 90 (1975) 1-19, 1975.
Inspire Record 91427 DOI 10.17182/hepdata.32062

We present the results of a formation experiment for the reaction K − p → Λπ 0 in the cms energy between 2200 and 2436 MeV with a total statistics of 10 eV/μb. A partial-wave analysis including these new data gives evidence for the existence of three resonances in the P 3 , D 5 and G 9 (or H 11 ) states in this mass region.

Invariant Cross-Section for the Inclusive Reaction $p + p \to p + X$ at 205 GeV/c

Whitmore, J. ; Barish, S.J. ; Colley, D.C. ; et al.
Phys.Rev.D 11 (1975) 3124, 1975.
Inspire Record 91102 DOI 10.17182/hepdata.24887

Inclusive proton production in pp interactions at 205 GeV/c is studied using the Fermi National Accelerator Laboratory (Fermilab) 30-in. bubble chamber. The invariant cross section is presented in terms of several kinematic variables and compared with similar data obtained from counter experiments at Fermilab and at the CERN Intersecting Storage Rings (ISR). An important feature of this experiment is that it provides data for much wider ranges of the four-momentum transfer than have been attained in the counter experiments. It also gives full information on the associated charged-particle multiplicity of every event, thus permitting a detailed investigation of how various kinematic quantities depend on this parameter.
