Non Abelian orbifold compactifications of the heterotic string    [PDF]

Sebastian J. H. Konopka

I consider the construction of heterotic orbifold models having a toroidal orbifold with non Abelian point group. I construct an explicit model based on the point group $S_3$ and calculate the spectrum and remnant symmetries. This model provides a simple example of rank reduction of the Yang--Mills gauge group directly in the string theory rather than in the effective field theory. I check consistency of the construction by verifying that all continous and discrete symmetries are non anomalous.
