LO, NLO, and NNLO parton distributions for LHC event generators
Journal of High Energy PhysicsWe present NNPDF4.0MC, a variant of the NNPDF4.0 set of parton distributions (PDFs) at LO, NLO and NNLO, with and without inclusion of the photon PDF, suitable for use with Monte Carlo (MC) event generators, which require PDFs to satisfy additional ...

Probing Spin Dependent Quark and Gluon Distributions Through Azimuthal and Polarization Asymmetries
EPJ Web of Conferences, 2016 Spin and transverse momentum dependent parton distributions - Generalized Parton Distributions, Transverse Momentum Distributions and related distributions - are at the interface between the QCD structure of the hadrons and observable quantities.

Evolution of colour correlated double parton distributions: a quantitative study
Journal of High Energy PhysicsDouble parton distributions satisfy the same evolution equations as ordinary single-parton densities, provided that the colours of the two partons are uncorrelated.

Nonperturbative evolution of parton quasi-distributions
Physics Letters B, 2017 Using the formalism of parton virtuality distribution functions (VDFs) we establish a connection between the transverse momentum dependent distributions (TMDs) F(x,k⊥2) and quasi-distributions (PQDs) Q(y,p3) introduced recently by X.

Generalized parton distributions: recent results
, 2005 I review progress on selected issues connected with generalized parton distributions. Topics range from the description of hard exclusive reactions to the spatial distribution of quarks in the nucleon and the contribution of their orbital angular ...

Next-to-Leading order approximation of polarized valon and parton distributions
, 2004 Polarized parton distributions and structure functions of the nucleon are analyzed in the improved valon model. The valon representation provides a model to represent hadrons in terms of quarks, providing a unified description of bound state and ...

Nuclear Parton Distributions with the LHeC
EPJ Web of Conferences, 2016 Nuclear parton distributions are far from being known today because of an infant experimental base. Based on design studies of the LHeC and using new simulations, of the inclusive neutral and charged current cross section measurements and of the strange,
