　　　 （ABSTRACT）

We present a model in which elementary particles and forces are
unified in the framework of quantum field theory in higher dimensions.
The particles include gauge bosons, quarks and leptons, as well as
the Higgs bosons and the forces include strong, weak, hypercharge
as well as Yukawa interactions. The model is based on
a simple group $SU(8)$ in six dimensions with $N=2$ supersymmetry.
The gauge symmetry, as well as supersymmetry is broken to
$SU(4) x SU(2)_L x SU(2)_R x U(1)^2$ with $N=1$ supersymmetry
upon compactification in four dimension on a $T2/Z_6$ orbifold.
