规范单态的电/磁对偶性

Electric/Magnetic Duality with Gauge Singlets

Steven Abel, James Barnard

摘要:

我们演示了如何在N}=1的SU(N)SQCD中利用规范单态来寻找新的Kutasov对偶性(即对偶理论的匹配依赖于非零超势)的例子,其中F_Q是夸克味和多代伴随,或反夸克,或反夸克.单线态的作用是大大简化手征环的截断,同时保持R对称性,同时允许磁理论中基本介子的明确识别。对偶理论满足所有通常的测试,包括高度非平凡的特胡夫特异常匹配条件。

英文摘要:

We demonstrate how gauge singlets can be used to find new examples of Kutasov duality (i.e. where the matching of the dual theories relies on a non-zero superpotential) in N}=1 SU(N) SQCD with F_Q flavours of quark and multiple generations of adjoints, or antisymmetrics, or symmetrics. The role of the singlets is to simplify greatly the truncation of the chiral ring whilst maintaining an R-symmetry, and at the same time allowing an unambiguous identification of the elementary mesons of the magnetic theory. The dual theories satisfy all the usual tests, including the highly non-trivial 't Hooft anomaly matching conditions.
