A Precise extraction of R = sigma-L / sigma-T from a global analysis of the SLAC deep inelastic e p and e d scattering cross-sections

Whitlow, L.W. ; Rock, Stephen ; Bodek, A. ; et al.
Phys.Lett.B 250 (1990) 193-198, 1990.

We report the extraction of R = σ L / σ T from a global analysis of eight SLAC deep inelastic experiments on e-p and e-d scattering performed between 1970 and 1985. Values of R p , R d , and R d − R p are determined over the entire SLAC kinematic range: 0.1⩽ x ⩽0.9 and 0.6⩽ Q 2 ⩽20.0 (GeV/ c ) 2 . We find that R p = R d . Measured values of R ( x , Q 2 ) are larger than predictions based on perturbative QCD and on QCD with the inclusion of kinematic target mass terms, indicating that dynamical higher twist effects may be important in the SLAC kinematic range.

Measurement of asymmetry in spin dependent e p resonance region scattering.

Baum, Guenter ; Bergstrom, M.R. ; Clendenin, J.E. ; et al.
Phys.Rev.Lett. 45 (1980) 2000, 1980.
Inspire Record 154062 DOI 10.17182/hepdata.20698

The first measurements are reported of the asymmetry in resonance-region scattering of longitudinally polarized electrons by longitudinally polarized protons. Data have been obtained at Q2=0.5 and 1.5 (GeV/c)2 in the missing-mass range W=1.1−1.9 GeV. Results are compatible with a multipole analysis of single-pion electroproduction. The spin-dependent behavior is consistent with a duality mechanism as in the unpolarized case.

Inelastic electron Scattering from Hydrogen at 50-Degrees and 60-Degrees

Atwood, W.B. ; Bloom, Elliott D. ; Cottrell, R.Leslie ; et al.
Phys.Lett.B 64 (1976) 479-482, 1976.
Inspire Record 108900 DOI 10.17182/hepdata.18790

Inelastic electron scattering cross sections have been measured for four-momentum transfers between 4.1 GeV 2 and 30.5 GeV 2 . At the large scattering angles of this experiment, the dominant contribution to the cross section comes from the W 1 structure function. In the conventional scaling variables, x and x ′, this structure function does not exhibit scaling behavior, and at fixed x or x ′ it is found to decrease with increasing four-momentum transfer.

Electron Scattering at 4-Degrees with Energies of 4.5-GeV - 20-GeV

Inspire Record 100597 DOI 10.17182/hepdata.4669

This paper presents the results of the analysis of a single-arm inelastic-electron-scattering experiment at an angle of 4°. We present data on the turnon of scaling in the low-q2 region 0.1<q2<1.8, the neutron-proton comparison at large values of the scaling variable ω, resonance excitation, and the shadowing in scattering from heavy nuclei.
