The Majorana Neutrinoless Double-Beta Decay Experiment

Understand

Neutrinoless double-beta decay searches play a major role in determining the nature of neutrinos, the existence of a lepton violating process, and the effective Majorana neutrino mass.

• The Majorana Collaboration proposes to assemble an array of HPGe detectors to search for neutrinoless double-beta decay in Ge-76.
• Our proposed method uses the well-established technique of searching for neutrinoless double-beta decay in high purity Ge-diode radiation detectors that play both roles of source and detector.
• The technique is augmented with recent improvements in signal processing and detector design, and advances in controlling intrinsic and external backgrounds.
