Educing GPDs from amplitudes of hard exclusive processes
M. V. Polyakov
The dual parametrization of generalized parton distributions (GPDs) is considered in details. We discuss which part of information about hadron structure encoded in GPDs [part of t…
Spatial image of reaction area from scattering I: SO_mu(2.1) algebra formalism
M. V. Polyakov, O. N. Soldatenko, A. N. Vall +1
We develop general formalism of how to relate scattering amplitudes for exclusive processes to spatial image of target hadron. More precisely we show how to determine the spatial d…
Tomography for amplitudes of hard exclusive processes
M. V. Polyakov
We discuss which part of information about hadron structure encoded in the Generalized Parton Distributions (GPDs) [part of total GPD image] can be restored from the known amplitud…
Breakdown of chiral expansion for parton distributions
N. Kivel, M. V. Polyakov
In the framework of the chiral perturbation theory we computed two- and three-loop corrections to the pion parton distributions which posses -function singularities at x->0. Thi…
Nucleon form-factors of the energy momentum tensor in the chiral quark-soliton model
K. Goeke, J. Grabis, J. Ossmann +4
The nucleon form factors of the energy-momentum tensor are studied in the large-Nc limit in the framework of the chiral quark-soliton model.
