Abstract

We consider bosonic string models with non-Abelian gauge excitations, whose Lie-algebra-valued currents are ‘‘twisted’’ by nontrivial automorphisms. The twisted models have the same critical dimension as the corresponding untwisted models; however, their respective spectra are radically different.
