dc.description.abstract	We investigate lepton-number violation in weak interactions with massive Dirac neutrinos. In the framework of a simple SU(3)L×U(1) electroweak model we find that neutrinos naturally acquire only Dirac masses at tree level, and for an odd number of lepton families, one neutrino remains massless. After a spontaneous breakdown of symmetry we find that the SU(2)×U(1) effective theory has lepton-number-violating currents which couple to the standard gauge bosons. Flavorconserving \|Δl\|=2 processes such as neutrinoless double-β decay are forbidden in the simplest model, but processes such as μ-+(A, Z)-->e++(A, Z-2) and K--->π+e-μ- are allowed.
