The Italian National Institute of Nuclear Physics (INFN) is an organization dedicated to the study of the fundamental constituents of matter, and 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 the INFN develops both in its own laboratories and in collaboration with the world of industry.

Moreover, INFN promotes the application of the skills, methods, and experimental techniques developed in the course of its own research to research in other fields, such as medicine, artistic preservation, and environmental protection. These activities are conducted in close collaboration with the academic world.

Groups 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.

Research activity at the INFN is carried out at two complementary types of facilities: the Divisions (Sezioni) and the National Laboratories. Each of the Divisions is located at a university physics department. The Divisions thus provide a direct connection between the Institute and the academic world.

INFN research activities are organized in five national groups, working on different projects:

  • Experimental particle physics with accelerators, also known as high energy physics, which studies the fundamental components and interactions of matter.
  • Experimental particle physics without accelerators, i.e. astroparticle physics and neutrino physics.
  • Nuclear physics and the behavior of nuclear matter in different conditions.
  • Theoretical physics: developing theories and models to explain physics phenomena.
  • Technological research: research and development of advanced technologies for physics experiments.

Fundamental contributions to the most significative discoveries in science: ATLAS and CMS experiments at CERN with the discovery of the Higgs boson, detection of Gravitational Waves by the Ligo/Virgo collaboration, measure of astroparticles with space based detectors (“PAMELA” e “FERMI”).
