Description

The LEGEND experimental program is a phased search for neutrinoless double-beta decay (0$\nu\beta\beta$) in the $^{76}$Ge isotope. The first phase, LEGEND-200, aims for a discovery sensitivity at a half life of 10$^{27}$ years and has a background index goal of below 0.5 cts/(FWHM t yr). LEGEND-200 has been operating at LNGS with 142 kg of high-purity germanium (HPGe) detectors and started taking low-background data in March 2023. Approximately 48.3 kg-yr of data has been extensively studied to assess the background composition and sensitivity of the experiment. In this talk, we will present the background rejection performance of the experiment in the region of interest and an updated half life limit for 0$\nu\beta\beta$ in the $^{76}$Ge isotope.
