Asymmetric ℤ 4 orbifolds of type IIB string theory revisited

Abstract

Abstract We construct freely acting asymmetric ℤ 4 orbifolds of type IIB string theory on T 5 preserving 24,16 or 8 supercharges in five dimensions. We show that these models are well-defined if the SO(8) lattice is chosen, instead of the SU(2)4 lattice, which was previously considered in the literature.
