Abstract

The search for neutrinoless double beta decay is a topic of broad and current interest in modern physics. Its discovery would prove unambiguously not only the existence of new lepton-number violating physics but also its connection to the origin of neutrino mass. The LEGEND collaboration follows the GERDA and MAJORANA collaborations and works to develop the largest $ ^{76} $Ge based neutrinoless double beta decay experiment. As a first phase, the LEGEND-200 experiment is being installed in the upgraded GERDA infrastructure at Laboratori Nazionali del Gran Sasso of INFN. It is based on 200 kg of high-purity germanium detectors and aims to reach a discovery sensitivity on the neutrinoless double beta decay half-life of 10$^{27}$ years. An overview of the LEGEND-200 setup and its status will be provided.
