# Specific scalar mass relations in SU(3) × SU(2) × U(1) orbifold model

@article{Kawamura1997SpecificSM, title={Specific scalar mass relations in SU(3) × SU(2) × U(1) orbifold model}, author={Y. Kawamura and Tatsuo C. Kobayashi and Tohru Komatsu}, journal={Physics Letters B}, year={1997}, volume={400}, pages={284-294} }

Abstract We study flat directions and soft scalar masses using a Z3 orbifold model with SU(3) × SU(2) × 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 parameters. Some specific relations among scalar masses are obtained.
