  1. European underground laboratories for Astroparticle Physics Lino Miramonti – 8 Feb 2007 Campinas - Sao Paulo (Brasil) Lino Miramonti – 8 Feb 2007 – Campinas - Sao Paulo (Brasil)

  2. What Astroparticle Physics is? Employs knowledges and techniques from particle physics in order to study cosmological and astrophysical aspects Astrophysics & Cosmology Particle physics Astroparticle physics Detects particles coming from space for particle physics studies Lino Miramonti – 8 Feb 2007 – Campinas - Sao Paulo (Brasil)

  3. Typical studies of astroparticle physics are: • Neutrino Physics (Solar, Supernova, Atmospherics, Geoneutrinos, neutrinos from reactors and from accelerators, etc..) • Cosmic Ray Physics • Rare Processes (double beta decay, proton decay etc..) • Dark Matter(WIMP’s) • Gravitational Waves • Nuclear Physics (Cross section measurements of astrophysics interest) • ……. Very little cross sections and/or very rare processes means to shield the detector apparatus from cosmic radiation Underground laboratories Lino Miramonti – 8 Feb 2007 – Campinas - Sao Paulo (Brasil)
