Neutrino mass and mixing
Cuoricino was a cryogenic bolometric detector operating in Gran Sasso Underground Laboratory, Italy, from March 2003 to June 2008.
With its 40.7 kg of 130TeO2 in the form of an array of 62 crystals it has set the currently lower limit on the halflife of 130Te against neutrinoless double beta decay, T1/2 = 2.94 x 10^24 y at 90% CL.
It has moreover proven the feasibility of the CUORE...

Neutrino mass and mixing
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...

Neutrino mass and mixing
It is shown that the Majorana nature of the heavy neutrinos $N_j$ having masses in the range of $M_j \sim (100 - 1000)$ GeV and present in the TeV scale type I and inverse see-saw scenarios of neutrino mass generation, is unlikely to be observable in the currently operating and future planned accelerator experiments (including LHC) due to the existence of very strong constraints on the...

Neutrino mass and mixing
In view of the fact that the data on neutrino mixing are still compatible with a situation where Bimaximal mixing is valid in first approximation and it is then corrected by terms of order of the Cabibbo angle, we present examples where these properties are naturally realized. The models are supersymmetric in 4-dimensions and based on the discrete non-Abelian flavour symmetry S4.
