INFN is the Italian research agency dedicated to the study of the fundamental constituents of matter and the laws that govern them. It conducts theoretical and experimental research in the fields of subnuclear, nuclear and astroparticle physics. All of the INFN’s research activities are undertaken within a framework of international competition, in close collaboration with Italian Universities on the basis of solid academic partnerships.
Scientific activities are managed by five National Scientific Committees (CSN) that act as advisory bodies to the governing council. CSN2 covers astroparticle physics performing studies of cosmic background radiation, cosmic rays, neutrinos, GWs, VHE gamma rays, rare particles, and particles that are thought to constitute dark matter. INFN drives the GW search and funds the Virgo experiment.
