Towards small-x resummed parton distribution functions [PDF]

open access: yes, 2017
We present preliminary results for fits of parton distribution functions (PDFs) which include the resummation of small-x logarithms at NLLx accuracy, performed in the NNPDF framework.

Impact of ATLAS measurements on PDFs

open access: yesEPJ Web of Conferences, 2015
A review of the ATLAS measurements sensitive to parton distribution functions is presented. The analyses use proton–proton collision data at center–of–mass–energy √s = 7 TeV collected at the Large Hadron Collider between April and November 2011.

Heavy-quark parton distribution functions and their uncertainties [PDF]

open access: yes, 2001
We investigate the uncertainties of the heavy-quark parton distribution functions in the variable avor number scheme. Because the charm- and bottom-quark parton distribution functions (PDFs) are constructed predominantly from the gluon PDF, it is a ...

Ad Lucem: Quantum Electrodynamic Parton Distribution Functions [PDF]

open access: yes, 2019
Parton Distribution Functions are sets of functions that provide the momenta distributions of the constituent particles within a hadron, typically the proton, at different energy scales. This thesis describes the inclusion of Quantum Electrodynamics (QED)

NUCLEAR MODIFICATION TO PARTON DISTRIBUTION FUNCTIONS AND PARTON SATURATION. [PDF]

open access: yes, 2006
We introduce a generalized definition of parton distribution functions (PDFs) for a more consistent all-order treatment of power corrections. We present a new set of modified DGLAP evolution equations for nuclear PDFs, and show that the resummed {alpha ...

Introduction to parton distribution functions

open access: yes, 2005
We provide an assessment of the impact of parton distributions on the determination of LHC processes, and of the accuracy with which parton distribution functions (PDFs) can be extracted from data, in particular from current and forthcoming HERA ...

Gluon distribution and mass decomposition of the pion and kaon

open access: yesEuropean Physical Journal C: Particles and Fields
We present the gluon distribution functions of the pion and kaon in small-x and large-x regions, and compare them with the results obtained from lattice QCD and continuum Schwinger function methods.

A parton shower consistent with parton densities at LO and NLO: Pdf2Isr

open access: yesEuropean Physical Journal C: Particles and Fields
We present a method for obtaining an initial-state parton shower model where the (backward) evolution fully consistent with the (forward) evolution of the collinear parton density used.
