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.

High-energy electroproduction and the constitution of the electric current
TL;DR: In this article, the asymptotic behavior of electroproduction cross sections is shown to contain information about the constitution of the electric current, and it is shown that the cross sections are a good indicator of the strength of electric currents.
Journal ArticleDOI
Harmonic sums, Mellin transforms and Integrals
TL;DR: In this article, the SUMMER algorithm is presented to deal with nested symbolic sums over combinations of harmonic series, binomial coefficients and denominators, and it treats Mellin transforms and the inverse Mellin transformation for functions that are encountered in Feynman diagram calculations.
Journal ArticleDOI
Singlet Parton Densities Beyond Leading Order
TL;DR: In this paper, the authors present a short summary of the results for the evolution of two-loop singlet parton densities for both spacelike and timelike processes.
Journal ArticleDOI
Automatized analytic continuation of Mellin–Barnes integrals
Michal Czakon,Michal Czakon +1 more
TL;DR: A package written in MATHEMATICA that automatizes typical operations performed during evaluation of Feynman graphs with Mellin–Barnes (MB) techniques, allowing to analytically continue a MB integral in a given parameter without any intervention from the user and thus to resolve the singularity structure in this parameter.
Journal ArticleDOI
New approach to evaluation of multiloop Feynman integrals: The Gegenbauer polynomial x-space technique
TL;DR: In this article, the Gegenbauer polynomial x -space technique for evaluating dimensionally regularized massless Feynman diagrams is formulated and the analytical evaluation of counterterms in the minimal subtraction scheme at any model and for any composite operator is really possible.
