Abstract
An abelian symmetry extension of the SM and its possible implicaton
for the
neutrino sector is considered. The symmetry breaking by a new scalar vev is
described and the resulting suppressed neutrino mass terms are determined.
From the known data, the strenghts of the corresponding suppressing effect
are derived and the associated new scales are approached.
