A Note on the Geometry of CHL Heterotic Strings
arXiv:hep-th/9711104 · doi:10.1016/S0370-2693(98)00156-7
Abstract
We present a few remarks on disconnected components of the moduli space of heterotic string compactifications on . We show in particular how the eight dimensional CHL heterotic string can be understood in terms of topologically non-trivial and $\Spin(32)/Z_2$ vector bundles over the torus, and that the respective moduli spaces coincide.
