Abstract

The primary goal of the XENON experiment consists in finding the first direct evidence for the existence of Dark Matter in the Universe via its scattering with xenon target nuclei in a dual-phase time projection chamber detector. The unprecedented low level of background reached demonstrated this detector technology to be suitable also for other exciting rare-events searches among which the neutrinoless double beta decay of 136Xe. The discovery of such a process will shed light on another fundamental challenge in physics nowadays about the nature of neutrinos. In this proceeding I will discuss the current status of neutrinoless double beta decay of 136Xe search in XENON1T. In the context of the advancement of the XENON program, XENONnT is currently collecting its first scientific data in the underground INFN Laboratori Nazionali del Gran Sasso in Italy. With its target mass of 5.9 tonnes of liquid xenon and designed with a high level of background reduction, the XENONnT experiment aims to increase the predecessor sensitivity in rare-events searches. In this proceeding I will also report on the ongoing sensitivity projection studies for neutrinoless double beta decay search in XENONnT.
