Abstract

If neutrinos are Majorana particles, i.e. fermions that are their own antiparticles, then neutrinoless double-beta (0vββ ) decay is possible. In such a process, two neutrons can simultaneously decay into two protons and two electrons without emitting neutrinos. Neutrinos being Majorana particles would explicitly violate lepton number conservation, and might play a role in the matter-antimatter asymmetry in the universe. The Majorana Demonstrator experiment is under construction at the Sanford Underground Research Facility in Lead, SD and will search for the neutrinoless double-beta (0vββ) decay of the 76Ge isotope. The goal of the experiment is to demonstrate that it is possible to achieve a sufficiently low background rate in the 4 keV region of interest (ROI) around the 2039 keV Q-value to justify building a tonne-scale experiment. In this paper, we discuss the physics and design of the Majorana Demonstrator, its approach to achieving ultra-low background and the status of the experiment.
