Fixed Point Resolution in Extensions of Permutation Orbifolds

Abstract

We determine the simple currents and fixed points of the orbifold theory $CFT\otimes CFT/{\mathbb{Z}}_2$, given the simple currents and fixed point of the original $CFT$. We see in detail how this works for the $SU(2{)}_k$ WZW model, focusing on the field content (i.e. $h$-spectrum of the primary fields) of the theory. We also look at the fixed point resolution of the simple current extended orbifold theory and determine the $S^J$ matrices associated to each simple current for $SU(2{)}_2$ and for the $B(n{)}_1$ and $D(n{)}_1$ series.
