Generalized Parton Distributions (GPDs) contain a wealth of information and have become a powerful tool for studying hadron structure. Deeply Virtual Compton Scattering (DVCS) is the golden channel to access GPDs. However, the detection of all final-state particles and the small cross section of the reaction make DVCS measurements challenging. The future Electron-Ion Collider (EIC) will provide eA collisions with a center-of-mass energy ranging from 20 to 140 GeV and a luminosity up to 10 34 cm −2 s −1. The highly polarized electron and hadron beams will enable helicity-dependent measurements, extremely useful to study GPDs at high energy.
I will describe my contributions to the backward end-cap homogeneous electromagnetic calorimeter of the future EIC detector, as well as to its far-forward tracking system (Roman Pots). I will also present projections for a nuclear DVCS channel, for which the performance of these two detectors are particularly crucial.
