We give an overview of the theory for generalized parton distributions. Topics covered are
their general properties and physical interpretation, the possibility to explore the three …

The generalized parton distributions, introduced nearly a decade ago, have emerged as a
universal tool to describe hadrons in terms of quark and gluonic degrees of freedom. They …

Traditionally, lattice QCD computations of generalized parton distributions (GPDs) have
been carried out in a symmetric frame, where the transferred momentum is symmetrically …

We outline in detail the properties of generalized parton distributions (GPDs), which contain
new information on the structure of hadrons and which enter the description of hard …

Recently, there have been some interesting developments involving off-forward parton
distributions of the nucleon, deeply virtual Compton scattering, and hard diffractive vector …

We review the present state of knowledge regarding the transverse polarisation (or
transversity) distributions of quarks. After some generalities on transverse polarisation, we …

We study the non-forward matrix elements of twist-2 QCD light-ray operators and their
representations in terms of skewed and double distributions, considering the pion as well as …

We estimate the leading order amplitudes for exclusive photon and meson electroproduction
reactions at large Q 2 in the valence region in terms of skewed quark distributions. As …

This report is based on a ten-week program on" Gluons and the quark sea at high-energies",
which took place at the Institute for Nuclear Theory in Seattle in Fall 2010. The principal aim …

Generalized parton distributions have been introduced in recent years as a suitable
theoretical tool to study the structure of the nucleon. Unifying the concepts of parton …
