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.

Electron form factors up to fourth order. - II@@@Электронные форм-факторы с точностью вплоть до четвертого порядка. II
TL;DR: In this article, the results of the analytic evaluation of the electron form factors and of their zero-momentum transfer values, up to the fourth order of the perturbative expansion of QED in the electric charge, are presented.

Spin physics and polarized structure functions
Bodo Lampe,Bodo Lampe,E. Reya +2 more
TL;DR: In this paper, a review on the theoretical aspects and experimental results of polarized deep inelastic scattering and of other hard scattering processes is presented, with a focus on the first moment of the polarized structure function in various factorization schemes, which is related to the axial anomaly, and on its relevance for understanding the origin of the proton spin.

Contribution of the second order gluonic Wilson coefficient to the deep inelastic structure function
E.B. Zijlstra,W.L. van Neerven +1 more
TL;DR: In this article, the order α s 2 correction to the deep inelastic Wilson coefficient for all parton subprocesses with a gluon in the initial state was presented.

Light-Cone Behavior of Perturbation Theory
TL;DR: In this paper, a technique introduced by Symanzik is used to derive a series of equations obeyed order by order in perturbation theory by the structure functions ${W}_{1}$ and $\ensuremath{
u}{W}_2}$ entering the cross section for inelastic electron scattering.
