关于S^4上N=2* super Yang-Mills的瞬子和超多重态质量

On the instantons and the hypermultiplet mass of N=2* super Yang-Mills on S^4

Takuya Okuda, Vasily Pestun

摘要:

通过阐明超多重态质量与保持N=2超对称性的质量形变理论的等变参数之间的关系,证明了具有任意规范群的四球上的N=4物理超杨-米尔斯理论没有瞬子贡献.正确的关系还意味着N=4规范群SU(2)的超共形杨-米尔斯理论对应于插入非平凡算子的环面上的刘维尔理论,而不是文献中所声称的恒等式。

英文摘要:

We show that the physical N=4 super Yang-Mills theory on a four-sphere with an arbitrary gauge group receives no instanton contributions, by clarifying the relation between the hypermultiplet mass and the equivariant parameters of the mass-deformed theory preserving N=2 supersymmetry. The correct relation also implies that N=4 superconformal Yang-Mills theory with gauge group SU(2) corresponds to Liouville theory on a torus with the insertion of a non-trivial operator, rather than the identity as have been claimed in the literature.
