CEA is a public research organisation established for research, development and innovation in the field of energy, information, health, technologies and fundamental research. It is a prominent player in the European Research Area and is involved in setting up collaboration projects with many partners around the world. Within Irfu, as part of the CEA missions, the Nuclear Physics Division (SPhN) is leading experimental and theoretical fundamental research in nuclear physics. SPhN activities are gathered around four research axes, among them the hadronic physics laboratory, which does experimental research at CERN/COMPASS and TJNAF, and QCD phenomenology. Moreover, SPhN is largely implicated in the definition of the future of hadronic physics, especially in the EIC project.

CEA has specific roles in NA2-Small-x, VA2-3DPartons, NA4-PREN, JRA4-TMD-neXt, JRA5-GPD-ACT, JRA6-Next-DIS and JRA14-MPGD_HP.

CEA has the responsibility of VA2-3DPartons (Valerio Bertone) and JRA6-Next-DIS (Daria Sokhan, Francesco Bossu).

EC funds in VA2-3DPartons, NA4-PREN, JRA4-TMD-neXt, JRA5-GPD-ACT, JRA6-Next-DIS and JRA14-MPGD_HP.
