چکیده

In the context of QCD, an analysis is presented of a compilation of eN deep-inelastic scattering data taken at SLAC. Included are data for FFP, Fgd, F;P-Fy and R. The interaction between the logarithmic scaling violation from c1 S and the power-law scaling violation from higher-twist terms is discussed. This interaction can affect the determination of the parameter A and can alter the predictions for the ratios of anomalous dimensions. Furthermore, we show that, in the context of QCD, higher-twist terms may be able to account for the observed value of R = oL/oT which appears to be anomalously large. Different experiments have made different assumptions for the value of R used in extracting F2 from their data. We show that these. differences can account for the discrepancies in the relative normalizations of F2 from these experiments and also can have a significant effect on the value of A obtained.

روش خودسازگار در محاسبه نسبت با استفاده از تابع ساختار و نسبت EMC هسته‌های He3 و H3

By using the convolution formalism which consists of Fermi motion and binding effect, we investigate the deep inelastic electron scattering from A=3 mirror in the deep-valence region. The initial valence quark input is taken from the GRVs (Gluck, Reya and Vogt) fitting procedure and the next-to-leading order QCD evolution on FP2 (x,Q2) which gives very good fit to the available data in the (x,Q...

Direct determination of the gluon density in the proton from jet cross sections in deep-inelastic scattering

A QCD analysis of jet production in deep-inelastic scattering is presented. The studies are based on recent measurements of jet cross sections in the H1 experiment at HERA which are directly sensitive to the gluon density in the proton. The inclusion of H1 data on the inclusive deep-inelastic scattering cross section enables us to perform a consistent, simultaneous determination of the quark an...

NLO QCD procedure of the semi-inclusive deep inelastic scattering data analysis with respect to the light quark polarized sea

The semi-inclusive deep inelastic scattering (SIDIS) process is considered. A theoretical procedure is proposed allowing the direct extraction from the SIDIS data of the first moments of the polarized valence distributions and of the first moment difference of the light sea quark polarized distributions in the next to leading QCD order. The validity of the procedure is confirmed by the respecti...
