In this article, the global analysis for parton distributions as a function of the QCD strong coupling strength αs was studied, and a new series of distributions that span the range 0.110 < αs(mZ) < 0.128 were presented.
Abstract
We study the global analysis for parton distributions as a function of the QCD strong coupling strength αs, and present a new series of distributions that span the range 0.110 < αs(mZ) < 0.128. We use these distributions to explore the correlation between αs and the gluon distribution; the viability of global analysis as a method to measure αs; and the dependence on αs of predictions for W, Z, inclusive jet, and Higgs boson production (b→H and gg→H) cross sections at the Tevatron and the LHC. We find that the uncertainty in αs is the dominant source of uncertainty for inclusive jet production at moderately small pT and for Higgs production at intermediate masses in the Standard Model.

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.
