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.

Heavy flavor production at high energy ep colliders
TL;DR: In this paper, the total production rates for heavy quark pairs due to gauge boson fusion processes at high energy colliders are evaluated, and the influence of thresholds on the measured scaling violations is investigated.

Calculation of Massive 2-Loop Operator Matrix Elements with Outer Gluon Lines
TL;DR: In this paper, massive on-shell operator matrix elements and self-energy diagrams with outer gluon lines are calculated analytically at O(α s 2 ), using Mellin-Barnes integrals and representations through generalized hypergeometric functions.

Top quark production at hera
U. Baur,J. J. van der Bij +1 more
TL;DR: In this article, the exact analytic expression for the single top production cross section, including all quark mass effects, was derived and evaluated for different values of the t-quark mass m t.
