球面上16超对称的规范理论

Gauge theories with 16 supersymmetries on spheres

Joseph A. Minahan, Maxim Zabzine

摘要:

给出了球上极大对称规范理论局域化的统一方法,包括$S^6$和$S^7$ .该方法遵循Pestun从10维超级Yang-Mills降维的方法。由此产生的理论有一个简化的$R$ -对称性,其中包括一个$SU(1,1)$子群,除了在四维中,因为共形不变性,完整的平面空间$R$ -对称性被保持,在七维中,$SU(1,1)$是平面空间$R$ -对称性。对于$S^6$和$S^7$的情况,我们讨论了这些理论的局限性,并给出了相应的矩阵模型的新结果。$S^6$和$S^7$的矩阵模型分别定性地类似于$S^4$和$S^5$上的矢量多重峰的矩阵模型。我们还讨论了瞬子在六维和七维情况下的贡献。

英文摘要:

We give a unified approach to localization of maximally symmetric gauge theories on spheres, including $S^6$ and $S^7$. The approach follows Pestun's method of dimensionally reducing from 10 dimensional super Yang-Mills. The resulting theories have a reduced $R$-symmetry which includes an $SU(1,1)$ subgroup, except in four dimensions where, because of conformal invariance, the full flat-space $R$-symmetry is maintained, and in seven dimensions where $SU(1,1)$ is the flat-space $R$-symmetry. For the case of $S^6$ and $S^7$ we discuss the localization of these theories and also present new results for the corresponding matrix models. The matrix models for $S^6$ and $S^7$ are qualitatively similar to the matrix models of a vector multiplet on $S^4$ and $S^5$ respectively. We also discuss the contributions of instantons in the six and seven dimensional cases.
