Inelastic electron proton scattering at small four-momentum transfers as a test of finite-energy sum rules

Moritz, J. ; Schmidt, K.H. ; Wegener, D. ; et al.
Nucl.Phys.B 41 (1972) 336-352, 1972.
Inspire Record 75163 DOI 10.17182/hepdata.45250

The twofold differential cross section for the inelastic scattering of electrons on protons wa was measured as a function of the scattered electron energy for an electron scattering angle of 12°. The kinematic region covered in this experiment was 0.3 (GeV/ c ) 2 < q 2 < 1.0 (GeV/ c ) 2 and W < 2.9 GeV. The Bloom-Gilman as well as the constant scattering angle sum rule of Rittenberg and Rubinstein were tested.

MEASUREMENTS OF SHADOWING IN LOW Q**2 ELECTROPRODUCTION ON NUCLEI

Bailey, J. ; Botterill, D.R. ; Montgomery, Hugh E. ; et al.
Nucl.Phys.B 151 (1979) 367-388, 1979.
Inspire Record 132234 DOI 10.17182/hepdata.34763

Measurements of inelastic electron scattering have been made in the range 2.2 < ν < 3.8 GeV and 0.1 < | Q 2 | < 0.3 (GeV/ c ) 2 , on a selection of nuclei ranging from hydrogen and deuterium to uranium, by measuring the scattered electron only. Detailed calculations have been made of the contribution of radiative tails to the measured yield. The results show a small ‘shadowing’ consistent with other electroproduction experiments, and also with photoproduction experiments in this ν range, but the shadowing decreases rapidly as | Q 2 | increases.

First Observation and Cross-section Measurement of $\nu_e e^- \to \nu_e e^-$

Allen, R.C. ; Bharadwaj, V. ; Brooks, G.A. ; et al.
Phys.Rev.Lett. 55 (1985) 2401, 1986.
Inspire Record 215874 DOI 10.17182/hepdata.20326

We report the first observation and cross-section measurement of νe+e−→νe+e−. Using neutrinos of energy less than 53 MeV, we observed 63±17 events consistent with ν+e−→ν+e−, of which 51±17 events are assigned to νe+e−→νe+e−. The resulting cross section, {[8.9±3.2(statistical) ±1.5(systematic)]×10−45 cm2/MeV} Eν, agrees with standard electroweak theory, rules out constructive interference between weak charged-current and neutral-current interactions, and begins to indicate the existence of interference between these two interactions.

Measurement of the Difference in R = $\sigma^-$l / $\sigma^-$t and $\sigma$(a) / $\sigma(D$) in Deep Inelastic $e D$, $e$ Fe and $e$ Au Scattering

Dasu, S. ; de Barbaro, P. ; Bodek, A. ; et al.
Phys.Rev.Lett. 60 (1988) 2591, 1988.
Inspire Record 260760 DOI 10.17182/hepdata.20155

We measured the differences in R=σLσT and the cross-section ratio σAσD in deep-inelastic electron scattering from D, Fe, and Au nuclei in the kinematic range 0.2≤x≤0.5 and 1≤Q2≤5 (Gev/c)2. Our results for RA−RD are consistent with zero for all x and Q2, indicating that possible contributions to R from nuclear higher-twist effects and spin-0 constituents in nuclei are not different from those in nucleons. The European Muon Collaboration effect is reconfirmed, and the low-x data from all recent experiments, at all Q2, are now in agreement.

Measurements of Transverse Quasielastic Electron Scattering From the Deuteron at High Momentum Transfers

Arnold, R.G. ; Benton, D. ; Bosted, Peter E. ; et al.
Phys.Rev.Lett. 61 (1988) 806, 1988.
Inspire Record 261496 DOI 10.17182/hepdata.20075

Cross sections for 180° inelastic electron scattering from deuterium were measured from breakup threshold to beyond the quasielastic peak for incident-beam energies of 0.843, 1.020, 1.189, and 1.281 GeV, corresponding to 0.75≤Q2≤2.57 (GeV/c)2. The data are in reasonable agreement with nonrelativistic models that include final-state interactions and meson-exchange currents. The scaling function F(y) for these data is generally in agreement with F(y) for forward-angle data at the same Q2. Values of GMn determined from the data are in good agreement with results from previous experiments.

Precision Measurement of R = $\sigma^-$l / $\sigma^- T$ and F(2) in Deep Inelastic Electron Scattering

Dasu, S. ; De Barbaro, P. ; Bodek, A. ; et al.
Phys.Rev.Lett. 61 (1988) 1061, 1988.
Inspire Record 262063 DOI 10.17182/hepdata.20079

We report new results on a precision measurement of the ratio R=σLσT and the structure function F2 for deep-inelastic electron-nucleon scattering in the kinematic range 0.2≤x≤0.5 and 1≤Q2≤10 (GeV/c)2. Our results show, for the first time, a clear falloff of R with increasing Q2. Our R and F2 results are in good agreement with QCD predictions only when corrections for target-mass effects are included.
