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 …

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 …

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 …

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 …

Hard exclusive π+ electroproduction is investigated within the handbag approach. The
prominent role of the pion-pole contribution is demonstrated. It is also shown that the …

We present a simple empirical parameterization of the x-and t-dependence of generalized
parton distributions at zero skewness, using forward parton distributions as input. A fit to …

Attempting to understand the origin of the intrinsic spin of the proton and neutron has been
an active area of both experimental and theoretical research for the past twenty years. With …

The amplitude for hard exclusive pseudoscalar meson electroproduction off nucleon
(nuclear) targets is computed in QCD within the leading α s ln Q 2/Λ QCD 2 approximation …
