Description
Direct detection experiments look for scattering events of dark matter with known Standard Model particles. Scattering on heavy nuclei is a promising approach to searching for heavy (above a few GeV) dark matter candidates. Liquid noble elements, like xenon, are especially suited because of their inert behavior, ability to be purified and be low in radioactivity.
XENONnT is the result of two decades of detector development for direct dark matter searches by the XENON collaboration. Starting in 2020 with a total xenon mass of 8.6 tons, the experiment is still collecting and analyzing data.
The collaboration has set some of the most stringent limits on dark matter interactions with nuclei and has measured coherent elastic neutrino-nucleus scattering (CEvNS) with solar neutrinos, pushing into the "neutrino fog." This measurement demonstrates XENONnT’s capabilities not just as a dark matter detector, but also as a powerful tool for rare-event searches, including neutrino physics, double beta decay, and axion searches. In this talk, the newest results are presented.
