With the lowest background level ever reached by detectors searching for rare-events, XENON1T
proved to be the most sensitive dark matter direct detection experiment on earth. The unprecedented
low level of radioactivity reached, made the XENON1T experiment suitable also for other
interesting rare-events searches including the neutrinoless double beta decay of 136Xe. In this
proceeding, I will report on the current status of neutrinoless double beta decay of 136Xe search
in XENON1T. Furthermore, in the context of the advancement of the XENON program, the next
generation experiment, XENONnT, designed with a high level of background reduction aiming
to increase the predecessor sensitivity in rare-events searches is currently under commissioning
phase in the underground National Laboratory of Gran Sasso (LNGS): it hosts 5.9 tonnes of
liquid xenon as a target mass. I will also discuss the ongoing sensitivity projection studies for
neutrinoless double beta decay search in XENONnT.
