The first results of the XENONnT experiment and an outlook to the future DARWIN observatory — •Andrii Terliuk for the XENON collaboration — Universität Heidelberg, Heidelberg, Germany — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

The nature of Dark Matter is one of the most important open questions in today's particle physics and cosmology. The XENONnT experiment at the Gran Sasso Laboratory in Italy aims to discover it using a dual-phase time projection chamber filled with 6 tonnes of liquid xenon. It was commissioned in 2021 and shows an excellent performance in terms of background and purity levels. In this talk we will present the status and results obtained with the first XENONnT science run. Furthermore, we will introduce the future DARWIN observatory that will have the mass of at least 50 tonnes of liquid xenon, while further improving background levels and purity.
