Non-universal Soft Scalar Masses in Superstring Theories

Abstract

We study soft scalar masses comparing with gaugino masses in 4-dimensional string models. In general non-universal soft masses are derived in orbifold models. We give conditions on modular weights to lead to the large non-universality in the soft scalar masses. This non-universality is applied to the unification of the gauge coupling constants in the minimal string model.
