Measurement of the production of a W boson in association with a charm quark in pp collisions at s√ = 7 TeV with the ATLAS detector [PDF]
, 2014 The production of a W boson in association with a single charm quark is studied using 4.6 fb−1 of pp collision data at s√ = 7 TeV collected with the ATLAS detector at the Large Hadron Collider.

Nonforward parton distributions [PDF]
Physical Review D, 1997 Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive electroproduction processes require a generalization of usual parton distributions for the case when long-distance information is accumulated in nonforward matrix elements of quark and gluon light-cone operators.

The multidimensional nucleon structure
EPJ Web of Conferences, 2016 We discuss different kinds of parton distributions, which allow one to obtain a multidimensional picture of the internal structure of the nucleon.

Parton distribution functions [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 Parton distribution functions give the probability to find partons (quarks and gluons) in a hadron as a function of the fraction x of the proton's momentum carried by the parton. They are conventionally defined in terms of matrix elements of certain operators.

Generalized Parton Distributions in the Deuteron [PDF]
Physical Review Letters, 2001 We introduce generalized quark and gluon distributions in the deuteron, which can be measured in exclusive processes like deeply virtual Compton scattering and meson electroproduction. We discuss the basic properties of these distributions, and point out how they probe the interplay of nucleon and parton degrees of freedom in the deuteron wave function.

Structure functions and parton distributions [PDF]
, 1991 Activities of the structure functions and parton distributions group is summarized. The impact of scheme-dependence of parton distributions (especially sea-quarks and gluons) on the quantitative formulation of the QCD parton model is highlighted.

European Physical Journal C: Particles and Fields, 2020 Generalized transverse momentum dependent parton distributions (GTMDs), as mother funtions of transverse momentum dependent parton distributions (TMDs) and generalized parton distributions (GPDs), encode the most general parton structure of hadrons.

Evolution of parton distributions [PDF]
Nuclear Physics B, 1997 I present a highly efficient method for evolving parton distributions in perturbative QCD. The method allows evolving the parton distribution functions according to any of the commonly-used truncations of the evolution equations (which differ in their treatment of higher-order terms).
