摘要:

我们制定工程5维超共形场论(SCFT)通过局部卡-丘3倍的M-理论紧化所需的几何条件。扩展分类的秩1的情况下,这是实现几何收缩del Pezzo表面嵌入在一个3倍,我们提出了一个详尽的分类本地3倍工程秩2 SCFT在5D。这个系统的分类证实了所有的秩2 SCFT预测规范理论参数可以实现为一致的理论,除了一个家庭被证明是非微扰不一致,从而排除了几何考虑。我们发现,所有秩2 SCFT下降从6d(1,0)SCFT紧化的一个圆上可能扭曲的自同构连同整体对称性周围的卡鲁扎-克莱因圈。这些结果支持了我们的猜想,即每个5d SCFT都可以从某个父6d(1,0)SCFT的圆紧化中得到。

英文摘要:

We formulate geometric conditions necessary for engineering 5d superconformal field theories (SCFTs) via M-theory compactification on a local Calabi-Yau 3-fold. Extending the classification of the rank 1 cases, which are realized geometrically as shrinking del Pezzo surfaces embedded in a 3-fold, we propose an exhaustive classification of local 3-folds engineering rank 2 SCFTs in 5d. This systematic classification confirms that all rank 2 SCFTs predicted using gauge theoretic arguments can be realized as consistent theories, with the exception of one family which is shown to be non-perturbatively inconsistent and thereby ruled out by geometric considerations. We find that all rank 2 SCFTs descend from 6d (1,0) SCFTs compactified on a circle possibly twisted with an automorphism together with holonomies for global symmetries around the Kaluza-Klein circle. These results support our conjecture that every 5d SCFT can be obtained from the circle compactification of some parent 6d (1,0) SCFT.
