N=2对偶与三维Z化

N=2 Dualities and Z Extremization in Three Dimensions

Brian Willett, Itamar Yaakov

摘要:

本文利用定域化方法研究了N = 2的三维超对称规范理论的对偶性。具体来说,我们考虑一个对偶由于Aharony涉及酉和辛规范群,这是类似的塞贝格对偶在四维,以及相关的对偶涉及陈-西蒙斯条款。这些理论的可能性,非平凡的反常尺寸的手征多重峰,以前很难检查。我们使用一个矩阵模型计算的配分函数两侧的对偶,变形的实质量和FI条款,并发现他们同意。结果提供了强有力的证据的有效性所提出的对偶。我们还评论最近提出的建议,在这样的理论使用本地化恢复确切的IR共形尺寸。

英文摘要:

We use localization techniques to study duality in N = 2 supersymmetric gauge theories in three dimensions. Specifically, we consider a duality due to Aharony involving unitary and symplectic gauge groups, which is similar to Seiberg duality in four dimensions, as well as related dualities involving Chern-Simons terms. These theories have the possibility of non-trivial anomalous dimensions for the chiral multiplets and were previously difficult to examine. We use a matrix model to compute the partition functions on both sides of the duality, deformed by real mass and FI terms, and find that they agree. The results provide strong evidence for the validity of the proposed dualities. We also comment on a recent proposal for recovering the exact IR conformal dimensions in such theories using localization.
