Positron initiated deeply virtual Compton scattering (DVCS) off $$^4$$ 4 He and $$^3$$ 3 He nuclei is described. The way the so-called $$d-$$ d - term could be obtained from the real part of the relevant Compton form factor is summarized, and the importance and novelty of this measurement is discussed. The measurements addressed for $$^3$$ 3 He targets could be very useful even in a standard unpolarized target setup, measuring beam spin and beam charge asymmetries only. The unpolarized beam charge asymmetries for DVCS off $$^3$$ 3 He and $$^4$$ 4 He are also estimated, at JLab kinematics and, for $$^4$$ 4 He, also at a configuration typical at the future Electron–Ion Collider. Incoherent DVCS processes, in particular the ones with tagging the internal target by measuring slow recoiling nuclei, and the unique possibility offered by positron beams for the investigation of Compton form factors of higher twist, are also briefly addressed.

In this talk, we present the analysis of a deeply virtual Compton scattering process off 4 He. This study is done within the impulse approximation approach including state-of-the-art models for the nucleonic and nuclear ingredients. A glimpse on the comparison between our results and the experimental data coming form Jefferson Lab is also given. The last part of this work is devoted to the description of the new Monte Carlo event generator based on the models presented in the main part of the talk. First results from the simulations performed at the kinematic conditions foreseen at the Electron Ion Collider are discussed demonstrating that there is a wide enough kinematical range to reach the tomography of 4 He and understand other possible aspects of the elusive nuclear parton dynamics.
