Outline of Research at the Start

XENONnT was built to detect WIMP dark matter particles. Its precursors have also proven its potential for many other searches and measurements in astroparticle and nuclear physics. Our XENON collaboration is leading the field in deriving statistically sound results from background limited searches.
