A simple string model of hadrons, which is in agreement with scaling, is applied to the deep inelastic scattering of electrons by the nucleon and is used to make predictions of the average charge and the types of particles produced. In particular, the total baryon number of the particles produced in the photon fragmentation region is shown to be 0 for x ~ 0 and 1 for x ~ 1, where x is the Bjorken scaling variable.

Covariant Field

The deep inelastic scattering on deuteron is considered in a fully covariant field theoretical approach. All calculations are performed within the Bethe–Salpeter formalism and the operator product expansion method. We obtain the explicit form of the nucleon contribution and mesonic exchange corrections to the deuteron structure function [Formula: see text]. The sum rules for the baryon number and energy-momentum of the deuteron are derived using the normalization condition of the Bethe–Salpeter amplitude and the virial theorem of field theory.

Parity Symmetry

Deep inelastic scattering is one of the best place to study hadron structures. In this paper we consider the target fragmentation region deep inelastic scattering process at leading twist. The calculations are carried out by applying the collinear expansion. In the collinear expansion formalism the multiple gluon scattering is taken into account and gauge links are obtained systematically and automatically. Quantum chromodynamics is a non-Abelian gauge theory of strong interactions in which parity symmetry can be violated by the nontrivial [Formula: see text]-vacuum tunneling effects. As a result, the axial vector current is induced. By defining and decomposing the parity-odd correlator we calculate both the parity-even and parity-odd contributions to the cross-section of the target fragmentation region deep inelastic scattering. We also present the positivity bounds for these fracture functions.

Scaling Region

Relying on previous results, that link entanglement entropy and parton distribution functions in deep inelastic scattering, and focusing on the small Bjorken scaling region we present here indications that gluon shadowing might indeed be explained as due to a depletion of the entanglement entropy, between observed and unobserved degrees of freedom, per nucleon within a nucleus, with respect to the free nucleon. We apply to gluon shadowing the general Page approach to the calculation of the entanglement entropy in bipartite systems, giving physical motivations of the results.
