Description
The formalism of Dyson-Schwinger equations is a powerful tool to study correlation functions in quantum field theory, but has also proved to yield an outstanding framework for the evaluation of hadron properties. Starting from state of the art continuum Schwinger calculations of pion's parton distribution function, we describe its extension to off-forward hadron kinematics, yielding the pion's generalized parton distribution. From that point on, we evaluate the amplitude for deeply virtual Compton scattering (DVCS) in the kinematic regime covered at the foreseen Electron-Ion Collider. Predictions for the event-rates and beam spin asymmetries to be observed are presented, revealing the dominance of gluon content within the pion in driving its response to DVCS at future electron-ion collider energies.
