摘要：

We study generic features related to matter contents and flat directions in Z(2n) orbifold models. It is shown that Z(2n) orbifold models have massless conjugate pairs, R and (R) over bar, in certain twisted sectors as well as one of untwisted subsectors. Using these twisted sectors, Z(2n) orbifold models are classified into two types. Conjugate pairs, R and (R) over bar,lead to D-flatness as [R] = [(R) over bar] not equal 0. We investigate generic superpotentials derived from orbifold models so as to show that this direction is indeed a flat direction.
