Anisotropic Solutions For Orbifold Moduli From Duality Invariant Gaugino Condensates

Abstract

The values of the $T$ and $U$ moduli are studied for those ${\mathbf{Z}}_N$ Coxeter orbifolds with the property that some of the twisted sectors have fixed planes for which the six-torus ${\mathbf{T}}^6$ can not be decomposed into a direct sum ${\mathbf{T}}^2⨁{\mathbf{T}}^4$ with the fixed plane lying in ${\mathbf{T}}^2$. Such moduli in general transform under a subgroup of the modular group $SL(2,Z).$ The moduli are determined by minimizing the effective potential derived from a duality invariant gaugino condensate.
