Icarus is the largest liquid Argon TPC detector ever built (~600 ton LAr mass). It smoothly operates underground at the LNGS laboratory in Gran Sasso since summer 2010, collecting data with the CNGS beam and with cosmics.
Liquid argon TPCs are really ``electronic bubble chambers'' providing a completely uniform imaging and calorimetry with unprecedented accuracy on massive volumes.

SNO+ is a multi-purpose Neutrino Physics experiment, succeeding to the Sudbury Neutrino Observatory by replacing heavy water with liquid scintillator. Its scientific goals are the search for neutrinoless double-beta decay, the study of solar neutrinos and antineutrinos from reactors and the Earth's natural radioactivity, as well as supernovae neutrinos. The experimental advantages of SNO+ are...

One of the fundamental open questions in elementary particle physics is the value of the neutrino mass and its nature of Dirac or Majorana particle. Neutrinoless double beta decay (DBD0v) is a key tool for investigating these neutrino properties and for finding answers to the open questions concerning mass hierarchy and absolute scale.
Experimental techniques based on the calorimetric...

UHECR (Ultra High Energy Cosmic Rays) were expected to be protons, whose spectra suffer of photopion opacity on cosmic CMB, the so called GZK cut off; AUGER did claimed on 2007 that such events were along the expected Super-Galactic plane with GZK cut off. However the same AUGER composition was favoring nuclei (and not nucleon); the recent absence of narrow angle clustering of UHECR as...

We use the Magnus expansion of the evolution operator in the adiabatic basis to find an approximate solution to the problem of three-neutrino oscillations in a medium with a symmetric, but otherwise arbitrary, density profile. We use an expression of the evolution operator for the neutrino system written as the product of three factors, each of them corresponding to an effective two-neutrino...
