Nuclear and Subnuclear Physics
Research in nuclear physics aims at the understanding of the rich variety of phenomena exhibited by the atomic nucleus. The Milano group performs experiments with radioactive nuclear beams at various laboratories. It has a strong expertise on gamma spectroscopy, and is involved in the development of innovative detectors and detection techniques; it has played an important role in the construction of the European detector AGATA based on gamma tracking. It is also active in the field of nuclear astrophysics, contributing to the measurement of cross sections of thermonuclear fusion reactions at astrophysically relevant energies, with the unique underground accelerator LUNA. The group participates in the AEGIS experiment at CERN, for the study of fundamental laws (Weak Equivalence Principle, CPT) with antimatter. (Read more)
Research in subnuclear physics aims at the understanding of the elementary constituents of the Universe and of their interactions. The Milano group is engaged both in experiments in particle physics performed with the use of accelerators and in astroparticle physics.
PARTICLE PHYSICS AT ACCELERATORS
The Milano group is active both at the High Energy Frontier and at the High Intensity Frontier. The group had and is having an important role in the construction, commissioning and operation of the calorimeter and of the pixel detector of the ATLAS experiment at the Large Hadron Collider (CERN). The group is presently involved in the exciting search for the Higgs boson, as well as for supersymmetric particles, a possible solution to Dark Matter enigma. The group and the INFN Computing center have contributed in an important way to the development of GRID computing and middleware software, and Milano host a TIER2 facility for the analysis of data from LHC. The group is also involved in B physics research, both in BABAR experiment at SLAC and in SuperB, a project of a new high luminosity e+e− flavour factory, to be built near Rome. (Read more)
The Milano group has a leading responsibility in the BOREXINO experiment, a massive underground detector made of ultrapure liquid scintillator. This unique detector is used to measure the spectrum of low-energy solar neutrinos, providing basic information on neutrino oscillations and on the physics of the sun. The experiment has also measured geoneutrinos for the first time. The group participates in the AUGER collaboration for the measurement, carried out at a site in Argentina, of ultra-high energy cosmic rays – the most energetic particles in the universe. The explanation of their origin, of their acceleration mechanism and of their nature is one of the main issues in astroparticle physics. The Milano group is involved in the construction of a new set of muon counters in order to discriminate between protons and heavy nuclei primaries cosmic rays. The group is also involved in the ICARUS experiment, a very large mass liquid argon detector operated at the Gran Sasso underground laboratory. ICARUS is performing neutrino oscillation studies with the CNGS neutrino beam coming from CERN, and in the near future it will be dedicated to a search for sterile neutrinos.(Read more)
