Partonic structure of nucleons and nuclei

M. Polyakov (RUB) / Y. Dong (IHEP)


We plan to employ a phenomenological effective Lagrangian approach to study the Generalised Parton Distributions of the nucleon and particularly also of light nuclei, like the deuteron and 3He. Furthermore we plan to investigate Double Parton Distributions (DPDs), i.e. the observables, which describe the correlations of partons in the nucleon and nuclei, in this Effective Field Theory. These studies are a natural extension of the investigations of the nucleon electromagnetic form factors done in the first funding period.
