INFN Logo INFN - Italy's National Institute for Nuclear Physics - is an organization dedicated to the study of the fundamental constituents of matter, which conducts theoretical and experimental research in the fields of subnuclear, nuclear, and astroparticle physics. Fundamental research in these areas requires the use of cutting-edge technologies and instrumentation, which INFN develops both in its own laboratories and in collaboration with the world of industry. These activities are conducted in close collaboration with the academic world.

INFN is heavily involved in Grid R&D and related activities and manages a large part of the Italian Production Grid, through the INFN Grid effort.

Researchers in INFN are involved in all the High Energy Physics experiments at CERN.
