چکیده
The role of generalized parton distributions in wide-angle exclusive reactions will be discussed. In contrast to deep virtual exclusive reactions the wide angle processes offer the possibility of investigating the generalized parton distributions at large momentum transfer.

Probing quark-distribution amplitudes through generalized parton distributions at large momentum transfer.
In the large momentum transfer limit, generalized parton distributions can be calculated through a QCD factorization theorem which involves perturbatively calculable hard kernels and light-cone parton distribution amplitudes of hadrons. We illustrate this through the H(q)(x,xi,t) distribution for the pion and the proton, presenting the hard kernels at leading order. As a result, experimental da...
متن کاملBaryon Form Factors at High Momentum Transfer and Generalized Parton Distributions
Nucleon form factors at high momentum transfer t are treated in the framework of generalized parton distributions (GPD’s). The possibility of obtaining information about parton high transverse momentum components by application of GPD’s to form factors is discussed. This is illustrated by applying an ad-hoc 2-body parton wave function to elastic nucleon form factors F1 and F2, the N → ∆ transit...
متن کاملSome numerical studies of the evolution of generalized parton distributions
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, and to the dependence on the squared momentum transfer t.
متن کاملGeneralized Parton Distributions
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-dimensional structure of hadrons at parton level, their potential to unravel the spin structure of the nucleon, their role in small-x physics, and efforts to model their dynamics. We review our understanding of the ...
متن کاملLight-Front Dynamics and Generalized Parton Distributions
High energy reactions necessarily involve large momentum transfer to the target’s constituents, which thus rebound near light speed. The experimentally observed correlation between initial and final states measures the system’s response along the light cone. A convenient theoretical description of such reactions is light-front dynamics where the properties of physical states are described along...
