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.

QCD corrections to F L (x, Q 2 )
TL;DR: In this paper, the authors performed a numerical study of the QCD corrections to the structure function FL(x, Q 2 ) in the HERA energy range and showed that the relative corrections to F cc L turn out to be scale dependent.

Comparison of Inclusive Charm and Beauty Cross Sections in Deep-inelastic Scattering at HERA with Theoretical Predictions
TL;DR: In this article, the measurements of inclusive charm and beauty cross sections in deepinelastic scattering $ep$ collisions at HERA are compared with the predictions of perturbative quantum chromodynamics from the CTEQ and MRST fitting groups, employing a range of theoretical schemes.

Comparison of inclusive charm and beauty cross sections in deep-inelastic scattering at HERA with theoretical predictions
TL;DR: In this article, the authors compared the predictions of perturbative quantum chromodynamics from the CTEQ and MRST fitting groups, employing a range of theoretical schemes, and discussed the differences in the theoretical predictions and the theoretical uncertainties investigated.

Heavy flavour production at HERA
TL;DR: In this paper, the experimental results, covering the region in four-momentum transfer squared Q2 from photoproduction (Q2≈0) to deep-inelastic scattering at high Q2 are compared in detail with theoretical predictions, based on QCD calculations in both leading order and next-to-leading order perturbative approaches.
