Tensor-polarized parton density in the N→Δ transition

open access: yesPhysics Letters B
The generalized parton distributions for transitions between baryon states with different masses have a forward limit in which they behave as parton densities (light-front momentum transfer Δ+,ΔT=0, energy transfer Δ−≠0).

GPDs in heavy meson production and Compton scattering

open access: yesEPJ Web of Conferences, 2016
Exclusive processes of heavy meson production and spacelike and timelike deeply virtual Compton scattering allow us to investigate the hadron structure in terms of Generalized Parton Distributions (GPDs).

Generalized Parton Distributions: recent results

open access: yes, 2016
International audienceAfter an introduction to the field of Generalized Parton Distributions, we present the latest Deep Virtual Compton scattering data recently released by the CLAS collaboration. We then show what is learned from them on the partonic 3-

Some Numerical Studies of the Evolution of Generalized Parton Distributions. [PDF]

open access: yes, 2007
We study the evolution behavior of generalized parton distributions at small longitudinal momentum fraction. Particular attention is paid to the ratio of a generalized parton distribution and its forward limit, to the mixing between quarks and gluons ...

Hadron tomography studies by generalized parton distributions and distribution amplitudes

open access: yesEPJ Web of Conferences, 2017
We discuss hadron-tomography studies for the nucleon and exotic hadrons by high-energy hadron reactions. First, the constituent-counting rule is explained for determining internal quark configurations of exotic-hadron candidates by scaling properties of ...

Generalized parton distributions of pion for non-zero skewness in AdS/QCD

open access: yesNuclear Physics B, 2018
We study the generalized parton distributions (GPDs) of pion for non-zero skewness by considering the leading |qq¯〉 Fock state component. Inspired from AdS/QCD light-front wave functions, we calculate the pion GPDs.

Prospects For Measurements Of Generalized Parton Distributions At COMPASS

open access: yes, 2007
The concept of Generalized Parton Distributions extends classical parton distributions by giving a 3-dimensional view of the nucleons, allowing to study correlations between the parton longitudinal momentum and its transverse position in the nucleon ...

An introduction to the Generalized Parton Distributions [PDF]

open access: yes, 2002
The concepts of Generalized Parton Distributions (GPD) are reviewed in an introductory and phenomenological fashion. These distributions provide a rich and unifying picture of the nucleon structure. Their physical meaning is discussed.

Generalized parton distributions I

open access: yes, 2001
I give a brief introduction to generalized parton distributions and to the phenomenology of the exclusive processes where they can be measured. (orig.)Available from TIB Hannover: RA 2999(01-079) / FIZ - Fachinformationszzentrum Karlsruhe / TIB ...

Generalized parton distributions for the pion in chiral perturbation theory

open access: yes, 2005
Generalized parton distributions provide a unified parameterization of hadron structure and allow one to combine information from many different observables.
