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.
Book ChapterDOI
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 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 QCD is reviewed for both unweighted and polarized hadron scattering.

C. Chang,K. W. Chen,D. J. Fox,A. Kotlewski,P. F. Kunz,L. N. Hand,S. W. Herb,A. Russell,Y. Watanabe,S. C. Loken,M. Strovink,W. Vernon +11 more
TL;DR: In this paper, scale non-invariance is observed in 150 and 56-GeV muon scattering from an iron target in the range $1l{q}^{2}l40$.

Quantization of the Yang-Mills Field.
Richard L. Arnowitt,S.I. Fickler +1 more
TL;DR: In this paper, the quantum Yang-Mills field is introduced to satisfy the requirement of invariance under isotopic phase transformations of the second kind, and the theory is then put into its first-order form, so as to make it amenable to quantization by the methods of the Schwinger action principle.
Journal ArticleDOI
Single-scale diagrams and multiple binomial sums
M.Yu. Kalmykov,O. L. Veretin +1 more
TL;DR: In this article, the e -expansion of several two-loop self-energy diagrams with different thresholds and one mass is calculated, and on-shell results are reduced to multiple binomial sums which values are presented in analytical form.

Mass divergences in two-particle inelastic scattering
Stephen B. Libby,George Sterman +1 more
TL;DR: FeFeynman integrals for two-particle inelastic scattering are studied in the limit that the ratio of particle masses to all relevant invariants vanishes as discussed by the authors. But their discussion applies to renormalizable field theories including quantum chromodynamics.
