Query: A Twist on Broken U(3)xU(3) Supersymmetry   What symmetry breaking would be required for gauginos from a supersymmetric
theory to behave like left-handed quarks of the Standard Model? Starting with a
supersymmetric SU(3)xSU(3)xU(1)xU(1) gauge theory, the 18
adjoint-representation gauginos are replaced with 2 families of 9 gauginos in
the (3,3*) representation of the group. After this explicit breaking of
supersymmetry, two-loop quadratic divergences still cancel at a unification
scale. Coupling constant unification is supported by deriving the theory from
an SU(3)xSU(3)xSU(3)xSU(3) Grand Unified Theory (GUT). Sin^2 of the Weinberg
angle for the GUT is 1/4 rather than 3/8, leading to a lower unification scale
than usually contemplated, ~10^9 GeV. After spontaneous gauge symmetry breaking
to SU(3)xSU(2)xU(1), the theory reproduces the main features of the Standard
Model for two families of quarks and leptons, with gauginos playing the role of
left-handed quarks and sleptons playing the role of the Higgs boson. An
extension to the theory is sketched that incorporates the third family of
quarks and leptons.
