Gluon GTMDs at nonzero skewness and impact parameter dependent parton distributions
European Physical Journal C: Particles and FieldsWe investigate the leading twist generalized transverse momentum dependent parton distributions (GTMDs) of the unpolarized and longitudinally polarized gluons in the nucleon.

Chromodynamic Lensing and Transverse Single Spin Asymmetries
, 2003 We illustrate how an axial asymmetry in impact parameter dependent parton distributions can give rise to an axial asymmetry for the transverse momentum of the leading quark in the photo-production of hadrons.

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.

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 ...

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.

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.

QED corrections to the evolution of parton distributions
, 2004 We study the systematic inclusion of QED corrections in the evolution of parton distributions. O(alpha) corrections modify the evolution equation for parton distributions.
