Description
The moduli space of heterotic strings compactified on a d-dimensional torus contains special points where the gauge symmetry is enhanced only to certain groups of rank (d+16). We state criteria, based on embeddings into the Narain lattice, to establish whether a gauge group occurs or not and describe how to obtain the corresponding moduli. Orbifold compactifications that realize the CHL strings with gauge groups of reduced rank (d+8) are also analyzed. For d=1,2 we obtain all the maximally enhanced gauge groups. Connections to the Swampland Program will be discussed.
