Measurements of R = $\sigma$(L)/sigma(T) for 0.03 < x < 0.1 and fit to world data.

The E143 collaboration Abe, K. ; Akagi, T. ; Anthony, P.L. ; et al.

Phys.Lett.B 452 (1999) 194-200, 1999.

Inspire Record 475305 DOI 10.17182/hepdata.28090

Measurements were made at SLAC of the cross section for scattering 29 GeV electrons from carbon at a laboratory angle of 4.5 degrees, corresponding to 0.03<x<0.1 and 1.3<Q^2<2.7 GeV^2. Values of R=sigma_L/sigma_T were extracted in this kinematic range by comparing these data to cross sections measured at a higher beam energy by the NMC collaboration. The results are in reasonable agreement with pQCD calculations and with extrapolations of the R1990 parameterization of previous data. A new fit is made including these data and other recent results.

Short-Range Nucleon-Nucleon Correlations Investigated with the Reaction C-12 (e, e-prime pp)

Kester, L.J.H.M. ; Hesselink, W.H.A. ; Kalantar-Nayestanaki, N. ; et al.

Phys.Rev.Lett. 74 (1995) 1712-1715, 1995.

Inspire Record 414880 DOI 10.17182/hepdata.19658

The reaction C12(e,e′pp) has been studied at an energy transfer ω=212MeV and a three-momentum transfer |q|=70MeV/c. The measured missing-energy spectrum shows a signature for knockout of proton pairs from (1p)2, (1p,1s), and (1s)2 states. A comparison of the data with a calculation, in which different processes leading to two-nucleon knockout are accounted for, shows that the measured cross section for the knockout of a (1p)2 pair can largely be attributed to short-range nucleon-nucleon correlations.

Measurement of the A-dependence of deep inelastic electron scattering

Gomez, J. ; Arnold, R.G. ; Bosted, Peter E. ; et al.

Phys.Rev.D 49 (1994) 4348-4372, 1994.

Inspire Record 359103 DOI 10.17182/hepdata.22575

Cross sections for deep-inelastic electron scattering from liquid deuterium, gaseous He4, and solid Be, C, Al, Ca, Fe, Ag, and Au targets were measured at the Stanford Linear Accelerator Center using electrons with energies ranging from 8 to 24.5 GeV. These data cover a range in the Bjorken variable x from 0.089 to 0.8, and in momentum transfer Q2 from 2 to 15 (GeV/c)2. The ratios of cross sections per nucleon (σAσd)is for isoscalar nuclei have been extracted from the data. These ratios are greater than unity in the range 0.1<x<0.3, while for 0.3<x<0.8 they are less than unity and decrease logarithmically with atomic weight A, or linearly with average nuclear density. No Q2 dependence in the ratios was observed over the kinematic range of the data. These results are compared to various theoretical predictions.

Phys.Rev.C 48 (1993) 1849-1863, 1993.

Inspire Record 365224 DOI 10.17182/hepdata.6186

The response function of nuclei in the quasielastic region at large momentum transfer (q≤10 fm−1) is measured for a series of nuclei, He4, C12, Al27, Fe56, and Au197, up to large values of the Bjorken scaling variables x<2.5.

Electroproduction of pi0 on the proton near threshold

Welch, T.P. ; Karen, P.H. ; Mitchell, J.H. ; et al.

Phys.Rev.Lett. 69 (1992) 2761-2764, 1992.

Inspire Record 344040 DOI 10.17182/hepdata.19808

The electroproduction of π0 on the proton was measured from 0 to 2.5 MeV above threshold for virtual-photon 4-momenta of -0.05 and -0.1 (GeV/c)2. The sum of the lowest-order contributing multipoles, a0=‖E0+‖2-εL‖L0+‖2, was determined with a precision an order of magnitude better than previously possible. Our results for a0 are consistent with present calculations. Our extracted value for ‖L0+‖2 at the ‘‘photon point’’ is in agreement with recent predictions.

Measurement of elastic electron - neutron scattering and inelastic electron - deuteron scattering cross-sections at high momentum transfer

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

Phys.Rev.D 46 (1992) 24-44, 1992.

Inspire Record 322422 DOI 10.17182/hepdata.18708

We have measured inelastic electron-deuteron, electron-proton, and electron-aluminum cross sections at 10° in the kinematic region between elastic deuteron scattering and the second resonance region at six beam energies between 9.8 and 21 GeV. The elastic electron-neutron cross section was extracted from the quasielastic data at Q2=2.5,4.0,6.0,8.0, and 10.0 (GeV/c)2. The ratio of elastic cross sections σnσp falls with increasing Q2 above 6 (GeV/c)2. The inelastic data are compatible either with y scaling (scattering from a single nucleon) or with ξ scaling (scattering from quarks).

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.
