High-Energy Inelastic e p Scattering at 6-Degrees and 10-Degrees

Cross sections for inelastic scattering of electrons from hydrogen were measured for incident energies from 7 to 17 GeV at scattering angles of 6° to 10° covering a range of squared four-momentum transfers up to 7.4 (GeV/c)2. For low center-of-mass energies of the final hadronic system the cross section shows prominent resonances at low momentum transfer and diminishes markedly at higher momentum transfer. For high excitations the cross section shows only a weak momentum-transfer dependence.

Inelastic electron-Proton Scattering at Large Momentum Transfers

Miller, Guthrie ; Bloom, Elliott D. ; Buschhorn, G. ; et al.
Phys.Rev.D 5 (1972) 528, 1972.
Inspire Record 67123 DOI 10.17182/hepdata.22355

Differential cross sections for electrons scattered inelastically from hydrogen have been measured at 18°, 26°, and 34°. The range of incident energy was 4.5 to 18 GeV, and the range of four-momentum transfer squared was 1.5 to 21 (GeVc)2. With the use of these data in conjunction with previously measured data at 6° and 10°, the contributions from the longitudinal and transverse components of the exchanged photon have been separately determined. The values of the ratio of the photoabsorption cross sections σSσT are found to lie in the range 0 to 0.5. The question of scaling of 2MpW1 and νW2 as a function of ω is discussed, and scaling is verified for a large kinematic range. Also, a new scaling variable which reduces to ω in the Bjorken limit is introduced which extends the scaling region. The behavior of σT and σS is also discussed as a function of ν and q2. Various weighted sum rules of νW2 are evaluated.

Comparisons of Deep Inelastic e p and e n Cross-Sections

Bodek, A. ; Breidenbach, M. ; Dubin, D.L. ; et al.
Phys.Rev.Lett. 30 (1973) 1087, 1973.
Inspire Record 83716 DOI 10.17182/hepdata.21415

Cross sections for inelastic scattering of electrons from hydrogen and deuterium were measured for incident energies from 4.5 to 18 GeV, at scattering angles of 18°, 26°, and 34°, and covering a range of squared four-momentum transfers up to 20 (GeVc)2. Neutron cross sections were extracted from the deuterium data using an impulse approximation. Comparisons with the proton measurements show significant differences between the neutron and proton cross sections.

LARGE ANGLE PROTON AND PION PRODUCTION IN DEEP INELASTIC ELECTRON SCATTERING

Ahrens, L. ; Berkelman, Karl ; Brown, G.S. ; et al.
Phys.Rev.D 9 (1974) 1894, 1974.
Inspire Record 80405 DOI 10.17182/hepdata.47134

We have measured ep, eπ+, and eπ− coincidences for scattered electrons in the range Q2=0.4 to 2.2 GeV2 and W=2 to 4 GeV. We find (a) that vector-meson production decreases with Q2 more rapidly than does the total virtual-photon-plus-proton cross section, more rapidly even than the prediction of simple vector dominance, (b) that the slope of the t distribution in ρ and ω production becomes flatter with increasing Q2 and seems to be at least approximately a function of the single variable xρ=(Q2+mρ2)2Mν, (c) that the fraction of final states containing a proton decreases with increasing Q2, (d) that in the central region of longitudinal momenta the inclusive π+ yield seems to increase relative to the π− yield as Q2 increases, and (e) that the average transverse momentum of π− is greater than of π+ in the central region of longitudinal momenta.

High-Energy Single-Arm Inelastic e - p and e - d Scattering at 6-Degrees and 10-Degrees

Poucher, J.S. ; Breidenbach, Martin ; Ditzler, W.R. ; et al.
Phys.Rev.Lett. 32 (1974) 118, 1974.
Inspire Record 81157 DOI 10.17182/hepdata.3374

Differential cross sections for electron scattering from hydrogen and deuterium in the deep-inelastic region show that the neutron cross section is significantly smaller than the proton cross section over a large part of the kinematic region studied. Although νW2d differs in magnitude from νW2p, it exhibits a similar scaling behavior.

The Ratio of Deep - Inelastic e-n to e-p Cross-Sections in the Threshold Region

Bodek, A. ; Dubin, D.L. ; Elias, J.E. ; et al.
Phys.Lett.B 51 (1974) 417-420, 1974.
Inspire Record 91646 DOI 10.17182/hepdata.27946

We report measurements of the ratio of the deep-inelastic electron-neutron to electron-proton differential cross sections in the threshold ( ω <3) region. The ratio was found to scale and to decrease monotically with decreasing ω . No violation of the quark model lower bound of 0.25 was observed in the ratio.
