Specific Scalar Mass Relations in SU(3)*SU(2)*U(1) Orbifold Model

Abstract

We study flat directions and soft scalar masses using a $Z_3$ orbifold model with $SU(3)\times SU(2)\times U(1)$ gauge group and extra gauge symmetries including an anomalous $U(1)$ symmetry. Soft scalar masses contain $D$-term contributions and particle mixing effects after symmetry breaking and they are parametrized by a few number of parameters. Some specific relations among scalar masses are obtained.
