Double Beta Decay

GERDA searches for neutrinoless double beta decay of Ge-76.
Diodes from the former Heidelberg-Moscow and IGEX experiments
as well as new ones with small area contacts have been
operated in the first phase of the experiment.
A blind analysis has been performed. After all selections
and calibrations were finalized, the unblinding took place
in June. The result from this phase is presented....

Double Beta Decay
Oral
The GERDA collaboration has recently unblinded data of Phase I.
In order to further improve the sensitivity of the experiment,
additionaly to the coaxial detectors used in GERDA Phase I 30
BEGe detectors made from germanium enriched in Ge-76 will be
deployed. BEGe detectors have superior PSD capability, thus the background can be further reduced.
The liquid argon surrounding the detector...

The Majorana Collaboration is constructing the Majorana Demonstrator, an ultra-low background, 40-kg modular Germanium detector array to search for neutrinoless double beta decay in Germanium-76. The P-Type Point Contact (PPC) design of the Demonstrator's germanium detectors allows for significant reduction of background through pulse-shape analysis. The low energy thresholds achievable by...

Double Beta Decay
Oral
The theoretical and phenomenological impact of recent results
on the lifetime of neutrinoless double beta decay from KamLAND-Zen,
EXO-200 and GERDA is discussed. In particular, the compatibility of the limits on the decay of Xenon and Germanium is investigated.
The possibility of double beta decay mechanisms different from light Majorana neutrino exchange is stressed. Typically these...
