Bilepton contributions to the neutrinoless double beta decay in the economical 3-3-1 model

Abstract

Possible contributions of the bilepton to the neutrinoless double beta $(\beta \beta {)}_{0\nu }$ decay in the economical 3-3-1 model are discussed. We show that the $(\beta \beta {)}_{0\nu }$ decay in this model is due to both sources--Majorana $<M_{\nu }{>}_L$ and Dirac $<M_{\nu }{>}_D$ 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 $<M_{\nu }{>}_L/<M_{\nu }{>}_D$, both the Majorana and Dirac masses simultaneously give contributions dominant to the decay. As results, constraints on the bilepton mass are also given.
