We present an improved determination of the strange quark and antiquark parton distribution functions of the proton by means of a global QCD analysis that takes into account a comprehensive set of strangeness-sensitive measurements: charm-tagged cross sections for fixed-target neutrino–nucleus deep-inelastic scattering, and cross sections for inclusive gauge-boson production and W-boson production in association with light jets or charm quarks at hadron colliders. Our analysis is accurate to… 
Deuteron uncertainties in the determination of proton PDFs
We evaluate the uncertainties due to nuclear effects in global fits of proton parton distribution functions (PDFs) that utilise deep-inelastic scattering and Drell–Yan data on deuterium targets. To
Can $\overline{\rm { MS}}$ parton distributions be negative?
It is common lore that Parton Distribution Functions (PDFs) in the $\overline{\rm { MS}}$ factorization scheme can become negative beyond leading order due to the collinear subtraction which is
Parton distributions in the SMEFT from high-energy Drell-Yan tails
Abstract The high-energy tails of charged- and neutral-current Drell-Yan processes provide important constraints on the light quark and anti-quark parton distribution functions (PDFs) in the large-x
Self-consistent determination of proton and nuclear PDFs at the Electron Ion Collider
We quantify the impact of unpolarized lepton-proton and lepton-nucleus inclusive deepinelastic scattering (DIS) cross section measurements from the future Electron-Ion Collider (EIC) on the proton
Machine learning of log-likelihood functions in global analysis of parton distributions
Modern analysis on parton distribution functions (PDFs) requires calculations of the log-likelihood functions from thousands of experimental data points, and scans of multidimensional parameter space
W+c-jet production at the LHC with NNLO QCD accuracy
In these proceedings, we highlight some aspects of the recent computation of NNLO QCD corrections for W production in association with a charm jet at the LHC. The results are presented in the form
Determination of the parton distribution functions of the proton using diverse ATLAS data from pp collisions at $$\sqrt{s} = 7$$, 8 and 13 TeV
This paper presents an analysis at next-to-next-to-leading order in the theory of quantum chromodynamics for the determination of a new set of proton parton distribution functions using diverse
Compatibility of Neutrino DIS Data and Its Impact on Nuclear Parton Distribution Functions
In global analyses of nuclear parton distribution functions (nPDFs), neutrino deep-inelastic scattering (DIS) data have been argued to exhibit tensions with the data from charged-lepton DIS. Using
nNNPDF3.0: evidence for a modified partonic structure in heavy nuclei
We present an updated determination of nuclear parton distributions (nPDFs) from a global NLO QCD analysis of hard processes in fixed-target lepton-nucleus and proton-nucleus together with collider
A new generation of simultaneous fits to LHC data using deep learning
Abstract We present a new methodology that is able to yield a simultaneous determination of the Parton Distribution Functions (PDFs) of the proton alongside any set of parameters that determine the

TLDR
A QCD analysis is reported of ATLAS data on inclusive W(±) and Z boson production in pp collisions at the LHC, jointly with ep deep-inelastic scattering data from HERA, which support the hypothesis of a symmetric composition of the light quark sea at low x.
