Neutrino-less Double Beta Decay and Particle Physics
Neutrino-less Double Beta Decay Particle Physics
2011/7/21
We review the particle physics aspects of neutrino-less double beta decay. This process can be mediated by light massive Majorana neutrinos (standard interpretation) or by something else (non-standard...

neutrinoless double-beta decay nuclear transition
2011/7/20
Neutrinoless double-beta decay nuclear transition matrix elements are generated by an effective two-body transition operator and it consists of Gamow-Teller like and Fermi like (also tensor) operators...

Performance of a large TeO2 crystal as a cryogenic bolometer in searching for neutrinoless double beta decay
large TeO2 crystal cryogenic bolometer cryogenic bolometer neutrinoless double beta decay
2011/7/20
Bolometers are ideal devices in the search for neutrinoless Double Beta Decay. Enlarging the mass of individual detectors would simplify the construction of a large experiment, but would also decrease...
Abstract: We use simple analytic considerations and a Monte Carlo calculation of nucleons in a box to argue that the use of Jastrow functions as short-range correlators in the commonly employed two-bo...

We present a search for beta plus/EC double beta decay of 120Te performed with the CUORICINO experiment, an array of TeO2 cryogenic bolometers. After collecting 0.0573 kg y of 120Te, we see no evidenc...
We present a search for β+/EC double beta decay of 120Te performed with the CUORICINO xperiment, an array of TeO2 cryogenic bolometers.
Neutrino masses and Neutrinoless Double Beta Decay: Status and expectations
Neutrino masses double beta decay
2010/3/15
Two most outstanding questions are puzzling the world of neutrino Physics: the possible Majorana nature of neutrinos and their absolute mass scale. Direct neutrino mass measurements and neutrinoless d...
Nuclear matrix elements (MGT) for two-neutrino double beta transitions of selected nuclei were calculated via a QRPA approach by considering the charge-exchange spin-spin interactions in the particle-...
