Abstract
In this paper we discuss a left-right symmetric model for elementary
particles
and their connection with the mass spectrum of
elementary fermions. The model is
based on the group
.
New mirror fermions
and a minimal set of Higgs particles that break this symmetry
down to
U(1)em are proposed. The model can accommodate
a consistent
pattern for
charged and neutral fermion masses as well as neutrino oscillations.
An
important consequence of the model is that the connection between
the left and
right sectors can be implemented by the neutral vector gauge
boson Z
and a new
heavy
Z'.
