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...
Spectral distribution method for neutrinoless double-beta decay nuclear transition matrix elements: Binary correlation results
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...

Search for beta plus/EC double beta decay of 120Te
Search beta plus/EC double beta decay 120Te
2010/12/29
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...
Density-dependent nuclear interactions and the beta decay of 14C: chiral three-nucleon forces and Brown-Rho scaling
Effective field theory at finite density chiral three-nucleon force Brown-Rho scaling
2011/1/7
We study the role of density-dependent low-momentum nucleon-nucleon interactions in describing the anomalously long beta decay lifetime of 14C. We approach this problem both from the perspective of ch...
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...
Investigation of Excited Levels in 193Ir From the Beta Decay of 193Os
Excited Levels 193Ir the Beta Decay of 193Os
2010/10/15
The excited states in 193Ir populated by the b¡ decay of 193Os were investigated via g-g coincidence analysis. Three levels at 517, 563 and 621 keV, previsouly seen only in nuclear reaction stud...
Pseudo-SU(4) Model and Beta Decay of pf-shell Nuclei
Pseudo-SU(4) Model Beta Decay pf-shell Nuclei
2010/10/25
The spectra and the beta decay of the Ni-Cu-Zn isotopes with A=58, 59 and 60 are studied by using the pseudo-SU(4) model.
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-...
