Neutrinoless double beta decay in the economical 3-3-1 model
Tóm tắt
Possible contributions to neutrinoless double beta (ββ)0ν decay in the economical 3-3-1 model are discussed. We show that the (ββ)0ν decay in this model is due to both sources—Majorana L and Dirac D neutrino masses. If the mixing angle between charged gauge bosons, the standard model W and bilepton Y , is in range of the ratio of neutrino masses L/D, both the Majorana and Dirac masses simultaneously give contributions dominant to the decay. As results, constraints on the bilepton mass are also given.
