The O(αs2) heavy quark corrections to charged current deep-inelastic scattering at large virtualities
TL;DR: In this paper, the heavy flavor corrections to charged current deep-inelastic scattering at large scales were calculated and the contributing Wilson coefficients were given as convolutions between massive operator matrix elements and massless Wilson coefficients.

Modeling deep inelastic cross sections in the few GeV region
Arie Bodek,U. K. Yang +1 more
TL;DR: In this paper, simple modifications and corrections to GRV94 leading order parton distribution functions such that they can be used to model electron,muon and neutrino deep-inelastic scattering cross sections at low energies are presented.

The Theory of Deeply Inelastic Scattering
TL;DR: In this paper, the theoretical status reached for both unpolarized and polarized lepton-hadron scattering based on perturbative Quantum Chromdynamics (QCD) is reviewed.

Nucleon spin structure functions at NNLO in the presence of target mass corrections and higher twist effects
TL;DR: In this article, the authors extract polarized parton distribution functions (PPDFs), referred to as ''KTA17'' together with the highly correlated strong coupling from recent and up-to-date polarized structure functions world data at next to next-to leading order in perturbative QCD, and their role in extracting the PPDFs in the nucleon is studied.

O(αs2) timelike Wilson coefficients for parton fragmentation functions in Mellin space
Johannes Blümlein,V. Ravindran +1 more
TL;DR: In this article, the Mellin moments of the O(α s 2 ) coefficient functions for the unpolarized and polarized fragmentation functions are calculated in terms of multiple finite harmonic sums of maximal weight w = 4.

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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.

Positivity constraints for anomalous dimensions
Otto Nachtmann,Otto Nachtmann +1 more
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.
