The Italian National Institute for Nuclear Physics (INFN) is an organization that conducts theoretical and experimental research in the fields of subnuclear, nuclear, and astroparticle Physics.

Fundamental research in these areas relies on cutting-edge technologies and instrumentation, which the INFN develops both in its own laboratories and in collaboration with Industry.

Moreover, INFN promotes the application of its own expertise and experimental techniques to research in other fields, such as medicine, cultural heritage preservation and environmental protection. These activities are conducted in close collaboration with the Academia.

Physicists from the Universities of Rome, Padua, Turin, and Milan founded INFN on August 8, 1951 for the purpose of building upon the scientific tradition established during the 1930's by Enrico Fermi and his School, with their theoretical and experimental research in nuclear physics.

INFN research is carried out at two complementary types of facilities: the Divisions (“Sezioni”) and the National Laboratories. INFN Divisions are located at the Physics Departments of major Italian Universities, providing a direct connection between the Institute and the Academia.

INFN research activities are organized in five national groups, which work in different research areas:

  • experimental particle Physics with accelerators, which studies the fundamental components of matter and their interactions;
  • experimental particle Physics without accelerators, i.e. astroparticle Physics, neutrino Physics and gravitational waves;
  • nuclear Physics and the study of nuclear matter in different conditions;
  • theoretical Physics: development of theories and models to explain the physical phenomena;
  • technological research: research and development of advanced technologies for physics experiments.

Fundamental contributions to the most significant discoveries in science: discovery of the Higgs boson by the ATLAS and CMS experiments at CERN, detection of gravitational waves by the LIGO/Virgo collaboration, measure of astroparticles with space based detectors (“PAMELA”, “GAPS” e “Fermi”).
