Astroparticle, space physics and INFN (Istituto Nazionale di Fisica Nuclare ) F Ronga INFN LNF Frascati INFN was established for nuclear and particle physics. Similar situation for other agencies around the world. Around 1980 supersimmetry ==> proton decay searches. In Italy NUSEX under the Mont Blanc. Beginning of a new interest for cosmic rays..also triggered by the CYGNUS X3 claim.. Then (1982) the Gran Sasso laboratory : main goals proton decay, monopole search, solar neutrinos... Increase of interest for cosmic rays and space (EAS-TOP first INFN experiment dedicated to cosmic rays) astroparticle physics in the years 1990 beginning of a “new field” : astroparticle physics

Astroparticle ApPEC: ApPEC: Several institutes In Europe (IN2P3, INFN…) joined together to form: ApPEC: ApPEC: AstroParticle Physics European Coordination An European “Road Map “ in progress Overlap eith other communities (astrophysics,particle physics..)

Don’t confuse this with the question “What belongs to Astroparticle Physics?” There is no unique answer to this question.

Charged Cosmic Rays GeV-TeV gamma (incl. DM indirect) HE neutrinos atm. neutrinos (incl. DM indirect) Solar axions underwater underice i.e. Hess, Auger CAST UG lab DM direct UG lab Solar Supernova WIMP satellite MeV/GeV  (Agile, Glast) MeV/GeV CR (Pamela, AMS) extreme energies (EUSO)

No particles from heaven but: - same infrastructure (  ) - closely related question (tritium decay)  UG lab Oscillations (accelerators)  NO proton decay Accelerator Laser axions m Reactor

Resonance Antennas Interferometers (Geo-600, VIRGO) Interferometer low frequency (LISA)

Nuclear astrophysics –Covered in nuclear physics programmes –In some countries listed under APP as well Dark Energy Missions –Necessary to set the stage for APP missions –Fully covered by astronomy community –Not our charge –In some countries under one roof with APP missions –We say what we support DE missions but do not specify Others –Varying fundamental constants –Equivalence principle –Gravity at short distances (may be included)

Astroparticle physics : INFN main searches in the scientific committee II neutrino physics (mass, oscillations..) cosmic ray origin and composition (ground and space) search for astrophysical sources of gamma rays and neutrinos search for gravitational waves on the ground and in space general physics (G measurement, equivalence principle, quantuum vacuum) Field in development : 2002 Nobel prizes for “astroparticle” (X astronomy, solar neutrinos, Supernova neutrinos)
