Nuclear response in electromagnetic interactions with complex nuclei
TL;DR: In this article, the response of nucleons and complex nuclei to an external electromagnetic probe at intermediate and high energy is illustrated by considering both inclusive and semi-inclusive electron scattering.

On determination of the large 1/x gluon distribution at HERA
TL;DR: In this paper, a correction to the leading-log Q2 relationship between the gluon density g(x, Q2) and FL(x and Q2), ∂FT(x, Q2)/∂ log Q2 in the HERA range of large 1 x was discussed.
Journal ArticleDOI
Deep inelastic scattering at HERA and the BFKL pomeron
TL;DR: In this paper, a BFKL phenomenology of structure functions in the framework of the generalized BFPL equation for the dipole cross section proposed by us recently is presented, and the HERA measurements of excitation of the charm at Q 2 ≲10 GeV 2 shall allow determination of the intercept of the BFKl pomeron.

Structure functions of bound nucleons: From the EMC effect to nuclear shadowing
TL;DR: In this article, a QCD-inspired model of nucleons, treated, in the limit of vanishingQ2, as bound states of three relativistic constituent quarks, is presented.
Journal ArticleDOI
Unitarization of structure functions at large 1/x
TL;DR: In this paper, the effects of the s -channel unitarization on the x and Q 2 dependence of structure functions were discussed and the results were in very good agreement with the existing NMC and the preliminary HERA data.

Scaling violations in inclusive e + e - annihilation spectra
TL;DR: In this paper, the origin of the observed scaling violations in the hadron spectra is investigated, and a simple parametrization for the heavy-quark fragmentation function is given which describes well recently measured charmed-meson spectra.

Colour transparency and scaling properties of nuclear shadowing in deep inelastic scattering
TL;DR: In this article, a perturbative QCD analysis of nuclear shadowing in the deep inelastic scattering at smallx in terms of the spatial wave function of virtual photons is presented.

Freedom at Moderate Energies: Masses in Color Dynamics
Howard Georgi,H. David Politzer +1 more
TL;DR: In this paper, the effects of quark and target masses in lepton-hadron scattering were discussed, assuming a color SU(3) gauge theory of strong interactions, and the best renormalization procedure is to specify all parameters in the Lagrangian (coupling constants and masses) as well as wave function normalizations at Euclidean momenta of scale M.

Radiatively generated parton distributions for high-energy collisions
M. Glück,E. Reya,Andreas Vogt +2 more
TL;DR: In this paper, the gluon and antiquark distributions of the nucleon are generated radiatively using the assumption that at some low resolution scale the nucleus consists entirely of valence quarks and valence-like gluons and simple parametrizations of the resulting (positive definite!) parton distributions are presented in the range 10−4≲x≦1 and 0.2≲Q2 ≲106 GeV2.

Scaling Violations and the Gluon Distribution of the Nucleon
M. Glück,E. Hoffmann,E. Reya +2 more
TL;DR: In this paper, an attempt is made to extract the gluon distributionG(x, Q2=4 GeV2) from the observed scaling violations of structure functions.
