Nuclear shadowing in deep inelastic scattering on nuclei: leading twist versus eikonal approaches
We use several diverse parameterizations of diffractive parton distributions, extracted in leading twist QCD analyses of the HERA diffractive deep inelastic scattering (DIS) data, to make predictions for leading twist nuclear shadowing of nuclear quark and gluon distributions in DIS on nuclei. We find that the HERA diffractive data are sufficiently precise to allow us to predict large nuclear s...
متن کاملTesting Parton Charge Symmetry at HERA
There are strong theoretical indications that the minority valence quark distributions in the nucleon may break charge symmetry by as much as 35%. We show that a comparison of eD deep inelastic scattering through the charged current, for example at HERA, could provide a direct test of this effect. This measurement is also be sensitive to an intrinsic component of the strange quark sea which lea...
متن کاملAnalyzing the nucleon spin in weak interaction processes at HERA energies
We investigate the possibility to measure the spin content carried by the different quark flavors in a nucleon by means of polarized deep inelastic scattering with W exchange at HERA. Such measurements require a polarized proton beam. The expected inclusive and semi inclusive asymmetries are sizable and for realistic luminosities the expected statistical accuracies are good enough to extract ne...
متن کاملDeuteron Structure Functions in the Context of Few-Body Physics
Few-body systems offer a unique challenge to those interested in deep-inelastic scattering. Using the deuteron as the simplest and most easily solvable nuclear system we review the main physics issues in the valence and sea quark regimes. For the former the key issue is the understanding of Fermi motion and binding corrections, and our ability to extract the ratio F n 2 /F p 2 as x→ 1. The most...
