Status of LEGEND - Progress on LEGEND-200 and Outlook towards ton-scale

ORAL

Abstract

The Large Enriched Germanium Experiment for Neutrinoless $\beta\beta$ Decay (LEGEND) is an experimental effort to search for neutrinoless double-beta decay in $^{76}$Ge. Using a phased approach, the collaboration aims to develop an experimental program with the discovery potential reaching a half-life beyond 10$^{28}$ years. \\ In the first 200-kg phase, LEGEND will use existing resources as appropriate to expedite physics results. I will give an overview and status report on LEGEND-200 whose first test and commissioning phase will start this year. Furthermore, my talk will have an outlook on LEGEND-1000, and the physics reach of the ton-scale effort. An overview will be given on the various ongoing R\&D e fforts which are needed to reach the desired sensitivity.
