Talk 3D Structure of the Nucleon: GPDs and Form Factors Joint GPD/Future

Speaker

Marie BOER (Virginia Tech)

Description

Double deeply virtual Compton scattering (DDVCS), corresponding to the scattering of a virtual photon off a quark, followed by the emission of a photon of a different virtuality (decaying into leptons), allows for a unique access to the Generalized Parton Distributions (GPDs) in the ERBL region. The main advantage of DDVCS is enabling the decorrelation between the x and $\xi$ dependence of GPDs , which is essential for tomographic interpretation, relying on their extrapolation to zero skewness. In this talk we will present our projections and experimental setup for a DDVCS experiment at JLab using the Solid spectrometer in Hall A and an 11 GeV electron beam. We will also discuss the potential and opportunities for DDVCS experiments at JLab Hall A/C.
