Witten anomaly in 4d heterotic compactificaitons with N $$ \mathcal{N} $$ = 2 supersymmetry
Abstract We showed that there is no SU(2) Witten anomaly in a large class of 4d N $$ \mathcal{N} $$ = 2 supersymmetric Heterotic string compactifications. The consistency conditions we consider are the modularity of the new supersymmetric index, the integrality of BPS indices, and the discrete Pecce...
