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.
Journal ArticleDOI
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.

Journal ArticleDOI
Global parton distributions with nuclear and finite- Q 2 corrections
TL;DR: In this paper, the authors presented three sets of next-to-leading order parton distribution functions (PDFs) determined by global fits to a wide variety of data for hard scattering processes.
Journal ArticleDOI
Operator product expansions near the light cone
TL;DR: In this paper, a generalization of the results about short distance (xμ → 0) behaviour in quantum field theory is presented, where the authors show that the light cone behaviour is similar to the one described in this paper.
Journal ArticleDOI
The method of differentiating under the integral sign
Gert Almkvist,Doron Zeilberger +1 more
TL;DR: A continuous version of the second author's ''proof machine'' for proving hypergeometric identities is used for finding the differential equation for R(x) satisfying the holonomic function F(x, y).
Journal ArticleDOI
Scaling Violations and the Gluon Distribution of the Nucleon
M. Glück,E. Hoffmann,E. Reya +2 more
TL;DR: In this paper, an attempt is made to extract the gluon distributionG(x, Q2=4 GeV2) from the observed scaling violations of structure functions.
Journal ArticleDOI
Parton Distribution Functions for Twist Four
TL;DR: In this paper, all O(1/Q2) corrections to leptoproduction are described by a small number of generalized multiparton distribution functions which depend only on the longitudinal momentum of the partons.
