Detection of very small Neutrino Masses in double-beta decay

In the last decade evidence has emerged for finite neutrino masses. However this remarkable result, based on the observation of neutrino oscillations, gives us no information on the absolute size of neutrino masses. We will describe a new method that may extend our direct mass sensitivity by about two orders of magnitude. This new technique, employing double-beta decay in xenon-136, will result in a challenging "atomic physics experiment in a particle physics detector".
