CTEQ parton distributions and flavor dependence of sea quarks
TLDR
The authors describes salient features of new sets of parton distributions obtained by the CTEQ Collaboration based on a comprehensive QCD global analysis of all available data The accuracy of the new data on deep inelastic scattering structure functions obtained by very high statistics NMC and CCFR experiments provides unprecedented sensitivity to the flavor dependence of the sea-quark distributions.About:

New generation of parton distributions with uncertainties from global QCD analysis
TL;DR: In this paper, a new generation of parton distribution functions with increased precision and quantitative estimates of uncertainties is presented, using a recently developed eigenvector-basis approach to the hessian method, which provides the means to quickly estimate the uncertainties of a wide range of physical processes at these high-energy hadron colliders, based on current knowledge of the parton distributions.

Dynamical parton distributions of the proton and small x physics
M. Glück,E. Reya,Andreas Vogt +2 more
TL;DR: In this article, the perturbative properties of parton distributions generated radiatively from a valence-like input at some low resolution scale are discussed with the aim of explaining the physical aspects underlying the reliability of the predicted distributions in the small-x region.

The Resummation of soft gluons in Hadronic Collisions
TL;DR: In this paper, the effects of soft-gluon resummation for the production of high mass systems in hadronic collisions were investigated and an expression consistent with the known leading and next-to-leading results was proposed, in which the coefficients grow much less than factorially.

TL;DR: It is demonstrated that the factorization scale dependence of the structure functions calculated in this approach is substantially less than those obtained in the fixed-order calculations, as one would expect from a more consistent formulation.

Parton distributions from a global QCD analysis of deep inelastic scattering and lepton pair production
TL;DR: Parton distribution functions consistent with neutrino and muon deep inelastic scattering as well as Drell-Yan pair production results have been extracted in this paper, where the dependence of the results on factors such as kinematic cuts in the data, heavy target corrections, and choice of initial functional form are also explored.
