Pushing the Limits of Dark Matter Detection: New Insights from the XENONnT Experiment
Abstract
Astrophysical and cosmological observations suggest the presence of a massive, non-luminous, non-relativistic, and non-baryonic dark matter component in the Universe. A well-motivated class of DM candidates is weakly interacting massive particles. Direct detection searches for WIMPs, with masses ranging from a few GeV/c² to tens of TeV/c², have been conducted using liquid xenon time projection chambers. These searches have yielded the most stringent limits to date on elastic spin-independent WIMP-nucleon cross-sections. In this context, the multi-staged XENON program at INFN Laboratori Nazionali del Gran Sasso aims to detect dark matter using two-phase liquid xenon time projection chambers of increasing size and sensitivity. The XENONnT experiment is the latest detector in the program, designed as an upgrade to its predecessor, XENON1T. It features an active target of 5.9 tonnes of cryogenic liquid xenon (with a total mass of 8.5 tonnes in the cryostat), along with many other novel systems (e.g., Radon background reduction and liquid purification). This seminar will focus on the recent achievements of the XENON experiment, presenting the WIMP search results and highlighting the experiment's extensive physics reach.
