Ghost particles: New limits on extremely rare decay

[unable to retrieve full-text content]Neutrinos are the most elusive particles having extremely weak interactions with all other particles. They have rather unusual properties and are even expected to be identical with their own antiparticles. So far this property is, however, not experimentally verified even though many studies of neutrinos over the last 60 years have already boosted our understanding of elementary particle physics. Now scientists have obtained new strong limits for the so-called neutrino-less double beta decay, which tests if neutrinos are their own antiparticles.
