Parton distributions from high-precision collider data

Richard D. Ball, +15 more
- 01 Jun 2017 - 
TL;DR: NNPDF31 as discussed by the authors is the first global set of PDFs determined using a methodology validated by a closure test, which is motivated by recent progress in methodology and available data, and involves both on the methodological side, parametrize and determine the charm PDF alongside the light-quark and gluon ones, thereby increasing from seven to eight the number of independent PDFs.

Parton distributions from high-precision collider data

Richard D. Ball, +14 more
- 01 Jun 2017 - 
TL;DR: A new set of parton distributions, NNPDF3.1, is presented, which updates NN PDF3.0, the first global set of PDFs determined using a methodology validated by a closure test, and investigates the impact of parametrizing charm and evidence that the accuracy and stability of the PDFs are improved.

Precise determination of the mass of the Higgs boson and tests of compatibility of its couplings with the standard model predictions using proton collisions at 7 and 8 TeV

Vardan Khachatryan, +2137 more
- 14 May 2015 - 
TL;DR: The couplings of the Higgs boson are probed for deviations in magnitude from the standard model predictions in multiple ways, including searches for invisible and undetected decays, and no significant deviations are found.

TL;DR: In this paper, a determination of parton distribution functions (ABM11) and the strong coupling constant alpha_s at next-to-leading order (NNLO) in QCD based on world data for deepinelastic scattering and fixed-target data for the Drell-Yan process is presented.

New generation of parton distributions with uncertainties from global QCD analysis

Jon Pumplin, +5 more
- 09 Aug 2002 - 
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.
