Measurement of the Magnetic Structure Function of the Deuteron at q2 = 1.0-(GeV/c)2

Martin, F. ; Arnold, R.G. ; Chertok, B.T. ; et al.

Phys.Rev.Lett. 38 (1977) 1320, 1977.

Inspire Record 109585 DOI 10.17182/hepdata.21023

At a square of the momentum transfer of 1.0 (GeV/c)2 the elastic scattering of electrons on deuterons has been measured at electron scattering angles of 8°, 60°, and 82°. From these data we have extracted a value of B(q2)=(0.59±1.20)×10−5 for the deuteron. This measurements extends the range in momentum transfer by almost a factor of 2 over the previous measurements.

A Partial Wave Analysis of the 3 pi System in the Reaction K- p --> pi+ pi- pi0 Lambda at 4.2-GeV/c

The Amsterdam-CERN-Nijmegen-Oxford collaboration Cerrada, M. ; Wagner, F. ; Chaloupka, V. ; et al.

A partial-wave analysis of the (3 π ) 0 system produced peripherally in the reaction K − p → π + π − π 0 Λ at 4.2 GeV/ c is presented. The observation of the weak Λ decay allows a determination of all the transversity production amplitudes except for two phases. The production of known resonances having decay modes other than 3 π is used to test the isobar model ansatz. Significant ω(783), φ(1020) and A 2 (1310) production is observed. The spin parity of the ω ∗ (1675) is established as 3 − . No evidence for production of other resonances, such as axial vector-mesons, is found.

Electroproduction of $\phi$ mesons

Dixon, Roger L. ; Galik, R. ; Herzlinger, M. ; et al.

Phys.Rev.Lett. 39 (1977) 516, 1977.

Inspire Record 120120 DOI 10.17182/hepdata.20949

We report measurements of the electroproduction of ϕ mesons from hydrogen at Q2 values of 0.23, 0.43, and 0.97 GeV2 with |t| varying from 0.125 to 1.3 GeV2 at each Q2 point. The data show no evidence for a Q2 dependence of the slope of the t distribution; the forward cross section falls with increasing Q2 as the square of the ϕ propagator; the decay angular distributions agree with the predictions of s-channel helicity conservation; and the ratio of the longitudinal to the transverse component increases linearly with Q2.

Measurement of Elastic electron - Neutron Cross-Sections Up to Q2 = 10-(GeV/c)2

Rock, Stephen ; Arnold, R.G. ; Bosted, Peter E. ; et al.

Phys.Rev.Lett. 49 (1982) 1139, 1982.

Inspire Record 179135 DOI 10.17182/hepdata.20575

The elastic electron-neutron cross section has been measured at four-momentum transfers squared (Q2) of 2.5, 4.0, 6.0, 8.0, and 10.0 (GeV/c)2 with use of a deuterium target and detection of the scattered electrons at 10°. The ratio of neutron to proton elastic cross sections decreases with Q2. At high Q2 this trend is inconsistent with the dipole law, form-factor scaling, and many vector dominance models, although it is consistent with some parton models.
