Sterile Neutrinos in Neutrinoless Double Beta Decay

Original language description

We study possible contribution of the Majorana neutrino mass eigenstate nuh, dominated by a sterile neutrino component, to neutrinoless double beta (0nubetabeta) decay. A special emphasis is made on accurate calculation of the corresponding nuclear matrix elements. From the current experimental lower bound on the 0nubetabeta-decay half-life of 76 Ge we derive stringent constraints on the nuh-nue mixing in a wide region of the values of nuh mass. We discuss cosmological and astrophysical status of nuh inthis mass region.
