Abstract

The Majorana Demonstrator is searching for neutrinoless double-beta decay in ⁷⁶Ge with two modular arrays of natural and ⁷⁶Ge-enriched germanium detectors. It is located at the 4850' level of Sanford Underground Research Facility in Lead, South Dakota, USA, and its total mass of germanium detectors is 44.1 kg, of which 29.7 kg is enriched. The analysis of the first 26 kg-yr of data provides an unprecedented energy resolution of 0.13% in the region of interest at 2039 keV and a background level of 15.4 ±2.0 counts/(FWHM t yr). It establishes the lower limit of the half-life of neutrinoless double beta decay as 2.7 10²⁵ yr in ⁷⁶Ge at 90% CL. This analysis will be summarized here with an emphasis on the energy determination.
