场论中的Anomaly消去与圆上的F-理论

Anomaly Cancelation in Field Theory and F-theory on a Circle

Thomas W. Grimm, Andreas Kapfer

摘要:

本文研究了四维和六维场论在圆紧化后得到的低维Kaluza-Klein理论中局域规范反常的表现。我们确定了一个方便的一组变换作用于整个塔的无质量和有质量的状态,并调查他们的行动的低能有效理论在库仑分支。该地图采用高维大规范变换,并精确地产生异常取消条件时,在三维和五维有效理论的单回路诱导陈-西蒙斯条款。由此产生的对称性在研究Calabi-Yau流形上的M-理论到F-理论极限中起着关键作用。例如,利用所有诱导多个阿贝尔规范群或非阿贝尔群的全解析F理论几何都承认一定的对称性这一事实,我们能够一般地证明这些模型中纯阿贝尔或纯非阿贝尔反常的抵消。

英文摘要:

We study the manifestation of local gauge anomalies of four- and six-dimensional field theories in the lower-dimensional Kaluza-Klein theory obtained after circle compactification. We identify a convenient set of transformations acting on the whole tower of massless and massive states and investigate their action on the low-energy effective theories in the Coulomb branch. The maps employ higher-dimensional large gauge transformations and precisely yield the anomaly cancelation conditions when acting on the one-loop induced Chern-Simons terms in the three- and five-dimensional effective theory. The arising symmetries are argued to play a key role in the study of the M-theory to F-theory limit on Calabi-Yau manifolds. For example, using the fact that all fully resolved F-theory geometries inducing multiple Abelian gauge groups or non-Abelian groups admit a certain set of symmetries, we are able to generally show the cancelation of pure Abelian or pure non-Abelian anomalies in these models.
