Parton distributions for the LHC
TL;DR: In this paper, a preliminary set of updated NLO parton distributions and their uncertainties determined from CCFR and NuTeV dimuon cross sections are presented, along with additional jet data from HERA and the Tevatron.

Approximation theory and methods, by M. J. D. Powell. Pp 339. £25 (hardcover), £8·50 (paperback). 1981. ISBN 0-521-22472-1/29514-9 (Cambridge University Press)
TL;DR: In this article, the authors consider the problem of finding the best approximation operator for a given function, and the uniqueness of best approximations and the existence of best approximation operators.

A Schematic Model of Baryons and Mesons
TL;DR: In this article, the authors assume that the strong interactions of baryons and mesons are correctly described in terms of the broken "eightfold way", and they are tempted to look for some fundamental explanation of the situation.
The renormalization of the axial anomaly in dimensional regularization
TL;DR: In this article, the prescription for the γ5 matrix within dimensional regularization in multiloop calculations is elaborated and the three-loop anomalous dimension of the singlet axial current is calculated.

The 3-loop QCD calculation of the moments of deep inelastic structure functions
TL;DR: In this article, the authors presented the analytic next-to-next-to leading perturbative QCD corrections in the leading twist approximation for the moments N = 2, 4, 6, 8 of the flavour singlet deep inelastic structure functions F2 and FL.
BookDOI
The Theory of Quark and Gluon Interactions
TL;DR: In this article, a unified presentation of the theory of quarks and gluons is presented, including perturbative aspects such as deep inelastic scattering, jets, Drell-Yan scattering, and exclusive processes, and nonperturbative ones such as current algebra and PCAC techniques, and instantons, together with an introduction to lattice QCD.
Journal ArticleDOI
Higher-order effects in asymptotically free gauge theories: (II). Flavour singlet Wilson operators and coefficient functions
TL;DR: In this paper, the anomalous dimensions of the twist-two flavour singlet operators in the Wilson expansion to two loops and the coefficient functions to order g 2 were calculated in the dimensional regularization scheme with the minimal subtraction renormalization prescription.
Book ChapterDOI
CP-Violation in the Renormalizable Theory of Weak Interaction
TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.

Harmonic Sums and Polylogarithms Generated by Cyclotomic Polynomials
TL;DR: The computation of Feynman integrals in massive higher order perturbative calculations in renormalizable Quantum Field Theories requires extensions of multiply nested harmonic sums, which can be generated as real representations by Mellin transforms of Poincare- iterated integrals including denominators of higher cyclotomic polynomials.
