1308.0344 (Jihn E. Kim)

Abelian discrete symmetries Z_{N} and Z_{nR} from string orbifolds    [PDF]

Jihn E. Kim
We show that Abelian discrete symmetries Z_{N} and Z_{nR} from string orbifolds result by assigning vacuum expectation values(VEVs) only to specified singlets. These singlets obtaining VEVs carry the gauge charges (of the covering U(1) gauge group) as multiples of N for Z_N and n for Z_{nR}. We explicitly show this realization in a Z_{12-I} orbifold model.
