Proceedings ArticleDOI
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.

Analytic renormalization via continuous space dimension
Giovanni M. Cicuta,E. Montaldi +1 more
TL;DR: In this article, the equivalence between analytic renormalization and additive renormalisation has been proved; each recipe may be transformed into the other one, modu/us a finite renormaliz~ation (a).

Electroproduction scaling in an asymptotically free theory of strong interactions
Howard Georgi,H. David Politzer +1 more
TL;DR: In this paper, the authors analyzed electroproduction in a non-Abelian gauge model of the strong interactions using the techniques of Christ, Hasslacher, and Mueller, and showed that the theory is asymptotically free and consistent with scaling up to logarithms.

HERACLES : an event generator for ep interactions at HERA energies including radiative processes
TL;DR: In this article, a Monte Carlo event generator simulating neutral and charged current ep interactions at HERA energies and beyond is described, and the present version 4.0 of the generator optionally treats the ep scattering either by means of structure-function parametrizations or on the basis of parton distribution functions in the framework of the quark-parton model.
Journal ArticleDOI
Second-order contributions to the structure functions in deep inelastic scattering (I). Theoretical calculations
TL;DR: In this article, a simple analytical expression for the next-to-leading corrections to the contributions to scaling violations of non-singlet, twist-two operators is presented, which allows continuation of the procedure to arbitrary orders in perturbation theory.

Non-planar massless two-loop Feynman diagrams with four on-shell legs
TL;DR: The non-planar Feynman diagram with seven massless, scalar propagators and four on-shell legs was calculated analytically in dimensional regularization by.
