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.

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.

The gluonic operator matrix elements at O (α s 2 ) for DIS heavy flavor production
TL;DR: In this article, the O(� 2 ) gluonic matrix elements for the twist-2 operators were calculated, which contribute to the heavy flavor Wilson coefficients in unpolarized deeply inelastic scattering in the region Q 2 ≫ m 2, up to the linear terms in the dimensional parameter ", (D = 4+").

Deep inelastic scattering: The early years
TL;DR: The 1990 Nobel Prize for Physics lecture is reprinted in this paper, where the author discusses the early research at the High Energy Physics Laboratory at Stanford in the 1950's and the building of the Stanford Linear Accelerator Center in the 1960's.
