论文摘要
我们表明，在大型的4D n = 2个超对称杂质弦线紧凑型中，没有SU（2）静态异常。我们认为的一致性条件是新的超对称指数的模块化，BPS索引的完整性和离散的Peccei-Quinn Shift对称性。我们还找到了一个例子，这些情况不足以证明该理论是无异常的。这表明世界表SCFT中有更多条件对于一致的弦弦压缩至关重要。
We showed that there is no SU(2) Witten anomaly in a large class of 4d 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 Peccei-Quinn shift symmetries. We also found an example where these conditions are not sufficient to show that the theory is anomaly free. This suggests that there are more conditions in the worldsheet SCFT essential for consistent string compactifications.
