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 کاملGENERALIZED PARTON DISTRIBUTIONS AT LARGE MOMENTUM TRANSFER a
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.
متن کاملProbing the Nucleon at Large Momentum Transfer
The central role of soft nucleon matrix elements in reactions of high energy electrons or real photons with nucleons is emphasized. These soft matrix elements are described in terms of skewed parton distributions. Their connections to ordinary parton distributions, form factors, Compton scattering and hard meson electroproduction is discussed.
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 کاملMeson twist - 4 parton distributions in terms of twist - 2 distribution amplitudes at large N c
In this particular isospin combination of structure functions the contribution of twist-2 operators cancels out exactly and twist-4 contributions are dominant. It is remarkable that in the large Nc limit the twist-4 distribution function of quarks in the pion can be reduced to a convolution of twist-2 pion distribution amplitudes. 2. One can read the contribution of four-quark twist-4 operators...
