具有N = 2超对称性的4d杂种优势紧化中的Witten Anomaly

Witten Anomaly in 4d Heterotic Compactificaitons with N = 2 Supersymmetry

Yuichi Enoki, Yotaro Sato, Taizan Watari

摘要:

我们证明了在一大类4d N = 2超对称杂化弦紧化中不存在SU(2)Witten反常.我们考虑的一致性条件是新的超对称指数的模块性,BPS指数的完整性,和离散的Peccei-Quinn移位对称性。我们还发现了一个例子,这些条件不足以表明该理论是无异常的。这表明在世界表SCFT中有更多的条件是一致的弦紧化所必需的。

英文摘要:

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.
