Impact of CLAS and COMPASS data on polarized parton densities and higher twist
TL;DR: In this paper, the impact of these data on polarized parton densities and higher twist effects has been studied, and it was shown that negative polarized gluon density cannot be ruled out on the basis of the present DIS data.

Operator product expansion in QCD in off-forward kinematics: separation of kinematic and dynamical contributions
TL;DR: In this article, a general approach to the calculation of target mass and finite t = (p′ − p)2 corrections in hard processes which can be studied in the framework of the operator product expansion and involve momentum transfer from the initial to the final hadron state was developed.

Non-Lagrangian Models of Current Algebra
TL;DR: In this article, an alternative to specific Lagrangian models of current algebra is proposed, in which scale invariance is a broken symmetry of strong interactions, as proposed by Kastrup and Mack.

Theory of Functions
TL;DR: In this paper, the authors pointed out that the distinction between "finite" and "infinite" is one which does not require definition, and that the authors' view is not the only accepted view.

High-energy electroproduction and the constitution of the electric current
TL;DR: In this article, the asymptotic behavior of electroproduction cross sections is shown to contain information about the constitution of the electric current, and it is shown that the cross sections are a good indicator of the strength of electric currents.

TL;DR: Wilson's operator product expansion is examined in this article, where it is shown how to project on operators of definite spin at finite Q2 consistency conditions for anomalous dimensions following from positivity using the moment problem.
