double-beta decay (0v[beta][beta]) studies are both the best way to determine the Majorana nature of the neutrino and determine its effective mass.
In order to prove this, scientists are working to detect "neutrinoless
double-beta decay" - a situation in which natural decay of Tellurium dioxide crystals results in neutrinos giving away photons, electrons, and antineutrons.

Zinc molybdate tetraoxide (ZnMo[O.sub.4]), which can be utilized as cryogenic scintillating bolometers for neutrinoless
double beta decay detection [1-3], has attracted interest in the last years as the host material for rare-earth ions [4-8].
The [[beta].sup.v] spectrum is expected to have definite spectrum corresponding to direct transition to levels in daughter nuclei in similarity to neutrinoless
double beta decay; one of the possible broadening that could occur is due to original energy distribution of neutrinos.
The topics include physics potential and motivations for a muon collider, meson/baryon/tetraquark supersymmetry from superconformal algebra and light-front holography, neutrino mass ordering in future neutrinoless
double beta decay experiments, searching for composite Higgs models at the Large Hadron Collider, and extensions of the Standard Model in multi-spinor field formalisms--visible and dark sectors.
Multi-majoron modes for neutrinoless
Nineteen student posters update the Borexino solar neutrino detector in Italy, the COBRA experiment searching for neutrinoless
double beta decay, the Germanium detector array, the Askar'yan radio array, the Karlsruhe tritium neutrino experiment, and the IceCube neutrino observatory.
Research at SURF is being conducted 4,850 feet beneath the earth's surface with the intention of building a 40-kilogram germanium detector, capable of detecting the theorized neutrinoless
double beta decay.
Topics include extra dimensions; The International Linear Collider; astrophysical aspects of neutrinos; leptogenesis; neutrino experiments; string theory, string model-building, and string phenomenology--a practical introduction; theoretical aspects of neutrino masses and mixings; searching for the Higgs boson; Z phenomenology and the LHC; neutrinoless
double beta decay; and supersymmetry in elementary particle physics.
Within months, Ettore Fiorini of the University of Milan-Bieocca in Milan, Italy, and his colleagues expect their stack of crystals to begin serving as a detector of the long-sought disintegration, known as neutrinoless
