Description
The XENONnT experiment is aiming for the direct detection of dark matter in the form of weakly interacting massive particles (WIMPs) using a dual-phase liquid xenon time projection chamber. The detector, operated at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, features a total liquid xenon mass of 8.5 tonnes, of which 5.9 tonnes are active. XENONnT has now successfully completed three science runs, achieving and maintaining exceptional levels of radiopurity throughout, with radon activities at the level of O(1) μBq/kg. The experiment has further continuously improved its background rejection capabilities, notably through the addition of gadolinium doping to the water Cherenkov neutron veto, significantly boosting its neutron detection efficiency. The latest results from the XENONnT WIMP search, obtained from the combined analysis of all three science run datasets, will be presented.
