  An alternative to the conventional see-saw mechanism is proposed to explain
the origin of small neutrino masses in supersymmetric theories. The masses and
couplings of the right-handed neutrino field are suppressed by supersymmetry
breaking, in a way similar to the suppression of the Higgs doublet mass, $\mu$.
New mechanisms for light Majorana, Dirac and sterile neutrinos arise, depending
on the degree of suppression. Superpartner phenomenology is greatly altered by
the presence of weak scale right-handed sneutrinos, which may have a coupling
to a Higgs boson and a left-handed sneutrino. The sneutrino spectrum and
couplings are quite unlike the conventional case - the lightest sneutrino can
be the dark matter and predictions are given for event rates at upcoming halo
dark matter direct detection experiments. Higgs decays and search strategies
are changed. Copious Higgs production at hadron colliders can result from
cascade decays of squarks and gluinos.
