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.

Journal ArticleDOI
The Massless Higher-Loop Two-Point Function
TL;DR: In this paper, a new method for computing massless Feynman integrals analytically in parametric form was introduced, which depends only on the topology of the graph and can be checked algorithmically.
Journal ArticleDOI
Massive Feynman diagrams and inverse binomial sums
TL;DR: In this paper, a number of higher-order terms of the polarization function of the neutral gauge bosons are constructed in terms of generalized polylogarithmic functions, for an arbitrary value of the argument which corresponds to an arbitrary values of the off-shell external momentum.
Journal ArticleDOI
Unravelling higher twists
TL;DR: In this paper, a method of deriving the first power corrections (1/Q 2 ) to the leptoproduction structure functions is presented, based directly on the manipulation of Feynman diagrams, in which the transverse components of momenta and the gluon field control both kinematic and dynamical power corrections.
Journal ArticleDOI
Higher Order QCD Effects in Inclusive Annihilation and Deep Inelastic Scattering
TL;DR: In this article, a parton model interpretation of the predictions of quantum chromodynamics in the process e+e−→hadron + anything was presented and the complete list of parameters needed for the study of the scaling violations of fragmentation functions up to the next-to-leading logarithmic approximation was given.

TL;DR: In this paper, an algorithm for the numerical evaluation of harmonic polylogarithms of arbitrary real argument is presented, implemented into a FORTRAN subroutine hplog.
