COBRA - Double beta decay searches using CdTe detectors
A new approach (called COBRA) for investigating double beta decay using CdTe semiconductor detectors is proposed. This will allow simultaneous measurements of 5 β−β− and 4 ββ emitters at once. Half-life limits for neutrinoless double beta decay of Cd and Te can be improved by more than one order of magnitude and sensitivities on the effective Majorana neutrino mass of less than 1 eV can be obta...
متن کاملDouble Beta Decay: Theory, Experiment, and Implications
Double beta decay is a rare spontaneous nuclear transition in which the nuclear charge changes by two units while the mass number remains the same. It has been long recognized as a powerful tool to study lepton number conservation in general, and neutrino properties in particular. Since the lifetimes of double beta decays are so long, the experiments on double beta decay are very challenging an...
متن کاملSuperNEMO – the next generation double beta decay experiment
The SuperNEMO experiment is being designed to search for neutrinoless double beta decay to test if neutrinos are Majorana particles. The experimental technique follows that of the currently running NEMO-3 experiment, which successfully combines tracking and calorimetry to measure the topology and energy of the final state electrons. Unique particle identification capabilities of SuperNEMO will ...
متن کاملCalorimeter R&D for the SuperNEMO Double Beta Decay Experiment
SuperNEMO is a next-generation double beta decay experiment based on the successful tracking plus calorimetry design approach of the NEMO3 [1] experiment currently running in the Laboratoire Souterrain de Modane (LSM). SuperNEMO can study a range of isotopes, the baseline isotopes are Se and possibly Nd. The total isotope mass will be 100– 200 kg. A sensitivity to a 0νββ half-life greater than ...
متن کاملNemo-3 Double Beta Decay Experiment: Lastest Results
Latest results on 0νββ, 0νχ 0 ββ and 2νββ decays of different isotopes from NEMO-3 double beta decay experiment are presented. In particular, new limits at 90% C.L. on neurtinoless double beta decay of 100 M o and 82 Se have been obtained, T 1/2 > 5.8 × 10 23 y and T 1/2 > 2.1 × 10 23 y, respectively.
