The eigenstates of a single massless Dirac particle confined in a linear potential are calculated exactly by direct solution of the Dirac equation. The electromagnetic structure functions are calculated from the Dirac wave functions of the ground and excited states of the particle by coupling to its conserved vector current. We obtain the longitudinal and transverse structure functions as a function of y=nu-q, where nu and q are the energy and momentum transferred to the target in its rest… 
Spin asymmetries for confined Dirac particles
We study the Bjorken x (or equivalently Nachtmann ξ) dependence of the virtual photon spin asymmetry in polarized deep inelastic scattering of electrons from hadrons. We use an exactly solved
Virtual photon asymmetry for confined, interacting Dirac particles with spin symmetry
Departement fu¨r Physik und Astronomie, Universit¨at Basel, Switzerland(Dated: February 4, 2008)We study the Bjorken x dependence of the virtual photon spin asymmetry in polarized deepinelastic
Scaling of Dirac fermions and the WKB approximation
We discuss a new method for obtaining the WKB approximation to the Dirac equation with a scalar potential and a timelike vector potential. We use the WKB solutions to investigate the scaling behavior
Solving the radial Dirac equations: a numerical odyssey
We discuss, in a pedagogical way, how to solve for relativistic wavefunctions from the radial Dirac equations. We first solve the equations for a linear Lorentz scalar potential, Vs(r), that provides
Spin and pseudospin symmetries and the equivalent spectra of relativistic spin-1/2 and spin-0 particles
We show that the conditions which originate the spin and pseudospin symmetries in the Dirac equation are the same that produce equivalent energy spectra of relativistic spin-1/2 and spin-0 particles

We apply a model for the study of quark-hadron duality in inclusive electron scattering to the calculation of spin observables. The model is based on solving the Dirac equation numerically for a

Final state interaction contribution to the response of confined relativistic particles
We report studies of the response of a massless particle confined by a potential. At large momentum transfer q it exhibits \tilde{y} or equivalently Nachtmann \xi scaling, and acquires a constant
Scaling of space and timelike response of confined relativistic particles
Abstract The response of a relativistic particle bound in a linear confining well is calculated as a function of the momentum and energy transfer, q , ν. At large values of | q | the response
SCALING, DUALITY, AND THE BEHAVIOR OF RESONANCES IN INELASTIC ELECTRON-- PROTON SCATTERING.
We propose that a substantial part of the observed behavior of inelastic electron-proton scattering is due to a nondiffractive component of virtual photon-proton scattering. The behavior of resonance
Deep inelastic scattering and final state interaction in an exactly solvable relativistic model
In the theory of deep inelastic scattering (DIS) the final state interaction (FSI) between the struck quark and the remnants of the target is usually assumed to be negligible in the Bjorken limit.
Structure functions are not parton probabilities
The common view that structure functions measured in deep inelastic lepton scattering are determined by the probability of finding quarks and gluons in the target is not correct in gauge theory. We

Quark-hadron duality is an interesting and potentially very useful phenomenon, as it relates the properly averaged hadronic data to a perturbative QCD result in some kinematic regimes. While duality

Abstract. We determine the uncertainties on observables arising from the errors on the experimental data that are fitted in the global MRST2001 parton analysis. By diagonalizing the error matrix we

Abstract We analyze data on deep inelastic scattering of electrons from the proton using ideas from standard many-body theory involving bound constituents subject to interactions . This leads us to
Evidence for valencelike quark-hadron duality
TLDR
The inclusion of low-momentum transfer data yields a scaling curve resembling deep inelastic neutrino-nucleus scattering data, suggesting a sensitivity to valencelike structure only.
