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.
