The LEGEND collaboration has published the first result of the 0νββ search from LEGEND-200 in Physical Review Letter 136, 022701 . The result is based on 61.0 kg yr of data with over half of which comes from our highest performing detectors, including newly developed inverted-coaxial detectors, and is characterized by an estimated background level of 0.5+0.3/−0.2  ⁢cts/(keV ton yr) in the 0νββ decay signal region. A combined analysis performed with data from GERDA, the MAJORANA DEMONSTRATOR, and LEGEND-200, reveals no evidence for a 0νββ signal, and sets a new observed lower limit at T1/2 > 1.9×1026 yr (90% C.L.), corresponding to an upper limit of the Majorana mass in the range of mββ < 75–200  meV. 

Our group invites applications for a postdoctoral research position focusing on the LEGEND experiment. The Liquid Argon Research Assembly (LARA) currently under development at NTU will be used to study next-generation wavelength-shifting materials and investigate HPGe detector characteristics in  cryogenic environments. The successful candidate will be responsible for all aspects of this facility, from design and setup to operation. The official call and the application process can be found here.
