The fundamental nature of dark or invisible matter remains one of the great mysteries of our time. A leading hypothesis is that dark matter is made of new elementary particles, with proposed masses and interaction cross sections spanning an enormous range. Amongst the technologies developed to search for dark matter particles, detectors based on liquefied noble gases are currently leading the...
With the installation of rare event search experiments in underground laboratories, very good passive and active shielding measures, and careful material selection, radioactive noble gases in xenon become the main underground source in rare event searches, along with solar and atmospheric neutrinos. In particular, these include the isotopes $^\mathrm{39}$Ar, $^\mathrm{85}$Kr, $^\mathrm{136}$Xe...
