The Target Tracker detector (TT) of the OPERA experiment was successfully used for the on-line neutrino events registration and the location of the neutrino events in the target bricks. The TT is built of 496 modules combined in 62 walls of 6.7 x 6.7 m2 which provide X-Y coordinates for particles registered in the detector. Each module is made of 64 plastic scintillator strips.

Recent detection of high-energy neutrinos (approximately 30 TeV - 1PeV range), most likely from astrophysical sources, by IceCube neutrino observatory ushers the era of Neutrino Astronomy. Poor angular resolutions of the dominantly cascade-type events prohibit identification of the sources, however. A cluster of 5 cascade events near the Galactic Center, although statistically not significant w ... More

Recently a new collaboration formed by merging the PICASSO and COUPP efforts to use superheated liquids for dark matter searches. The collaboration is currently operating two bubble chambers at SNOLAB and is planning to design and build a new, large 250 l detector in the coming years. The status of the current runs and the reach of the new detector will be reported.

The so called 3-3-1 models, with gauge symmetry  SU(3)c X SU(3)L X U(1)x, are interesting extensions of the standard model (SM). The main feature of these models is that, by choosing appropriately the representation content, the triangle anomalies cancel out and  the number of families has to be a multiple of three, moreover because of the asymptotic freedom this number is just three. In particu ... More

Recent work on the reactor neutrino flux prediction, and the re-analysis of former short baseline experiments that followed, revealed the so called reactor anti-neutrino anomaly. The observed deficit of detected rates could be interpreted as an oscillation toward a new neutrino state, triggering thus a new interest for the search of light sterile neutrinos. The Stereo project aims to evidence—or ... More

The SuperNEMO detector, which builds on the highly successful NEMO project, will search for neutrinoless double beta decay at the Modane Underground Laboratory on the French-Italian border. If observed, neutrinoless double beta decay would show that the neutrino is its own antiparticle, would be the first evidence for total lepton number violation, and would allow a measurement of the absolut ...

SuperNEMO exploits the tracking-calorimetry technique pioneered by NEMO3. The key feature of SuperNEMO is its unique capability to fully reconstruct the kinematic of the event. This allows to reduce the backgrounds and to discriminate among different mechanisms behind the possible double beta decays.

The frequency with which a neutrino oscillates is dictated by its energy. Therefore, in order to determine neutrino oscillation parameters, experiments must accurately measure the energy of each neutrino. Unfortunately, the neutrino energy is not directly observable, and, instead, experiments can only measure the outgoing charged lepton from a charged current neutrino interaction, and perhaps some ...

The Project 8 experiment aims to measure the neutrino mass using tritium beta decays. Beta-decay electron energies will be measured using the beta-decay electrons' cyclotron radiation: as the electrons travel in a uniform magnetic field, the frequency of the cyclotron radiation is inversely proportional to their total relativistic energies. By observing the cyclotron radiation we can make a prec ... More
