The Particle Physics Division (DPhP)

Research unit


The DPhP, Particle Physics Division, is part of the Institute of Research into the Fundamental Laws of the Universe (Irfu), within the Matter and Universe Direction of CEA. The research program of the division is focused on three domains: elementary particles physics, observation cosmology and astroparticles, and energetic content of the Universe. The DPhP is also involved in instrumental developments necessary to lead research in collaboration with technical services, and is concerned about their impact on societal applications.
