We present a determination of parton distribution functions (ABM11) and the strong coupling constant alpha_s at next-to-leading order and next-to-next-to-leading order (NNLO) in QCD based on world data for deep-inelastic scattering and fixed-target data for the Drell-Yan process. The analysis is performed in the fixed-flavor number scheme for n_f=3,4,5 and uses the MSbar-scheme for alpha_s and the heavy-quark masses. At NNLO we obtain the value alpha_s(M_Z) = 0.1134 +- 0.0011. The fit results are used to compute benchmark cross sections at hadron colliders to NNLO accuracy and to compare to data from the LHC.

Inelastic electron scattering from hydrogen at 50° and 60°☆

Values of R = sigma/sub L//sigma/sub T/ for deep-inelastic electron-nucleon scattering have been derived from several experiments with incident electron energies up to 20 GeV. Included are previously unpublished measurements at intermediate angles (largely at 15/sup 0/ and 18/sup 0/). An average value of R = 0.22 +- 0.1 is obtained for the kinematic region covered by the experiments. No significant kinematic dependence of R is observed. A table of extracted values of the structure functions ..nu..W/sub 2/ and 2MW/sub 1/ is also presented.

Ratio sigma/sub L//sigma/sub T/ from deep-inelastic electron scattering

We have measured the ratio, Y/sup +//Y/sup -/, of positron to electron inelastic scattering yields from hydrogen and deuterium at Q/sup 2/, the square of the four-momentum transfer, between 2.4 and 14.9 (GeV/c)/sup 2/. The ratios are consistent with Y/sup +//Y/sup -/=1 to within errors of a few percent. (AIP)
