Bilepton contributions to the neutrinoless double beta decay in the economical 3-3-1 model
Possible contributions of the bilepton to the 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}/< M_ν>_{D}$, both the Majorana and Dirac masses simultaneously give contributions dominant to the decay. As results, constraints on the bilepton mass are also given.
