M5-Branes、D4-Branes和Quantum 5D super-Yang-Mills

M5-Branes, D4-Branes and Quantum 5D super-Yang-Mills

Neil Lambert, Constantinos Papageorgakis, Maximilian Schmidt-Sommerfeld

摘要:

我们重新讨论了在圆上紧化的六维(2,0)M5-膜共形场论与五维最大超对称杨-米尔斯规范理论的关系.我们表明,在破碎阶段5D的超杨米尔斯包含的孤立子状态,可以确定与完整的卡鲁扎-克莱因模式的M2-膜结束的M5-膜的频谱。这提供了一个证据,证明圆上的(2,0)理论等价于没有额外UV自由度的5D超杨-米尔斯,表明后者实际上是一个定义良好的量子理论,并且可能是有限的。

英文摘要:

We revisit the relation of the six-dimensional (2,0) M5-brane Conformal Field Theory compactified on a circle to 5D maximally supersymmetric Yang-Mills Gauge Theory. We show that in the broken phase 5D super-Yang-Mills contains a spectrum of soliton states that can be identified with the complete Kaluza-Klein modes of an M2-brane ending on the M5-branes. This provides evidence that the (2,0) theory on a circle is equivalent to 5D super-Yang-Mills with no additional UV degrees of freedom, suggesting that the latter is in fact a well-defined quantum theory and possibly finite.
