Generalized Parton Distributions and Description of Electromagnetic and Graviton form factors of nucleon

Understand

The new parameterization of the generalized parton distributions t-dependence is proposed.

• It allows one to reproduce sufficiently well the electromagnetic form factors of the proton and neutron at small and large momentum transfer.
• The description of the data obtained by the Rosenbluth method and the polarization method are compared.
• The results obtained by the latter method are shown to be compatible with the correspondent neutron data.
