通有环面奇点的M2-brane理论

Towards M2-brane Theories for Generic Toric Singularities

Sebastian Franco, Amihay Hanany, Jaemo Park, Diego Rodriguez-Gomez

摘要:

我们构造了几个(2+1)维N=2超对称Chern-Simons理论的例子,其模空间由非紧复曲面的Calabi-Yau四重给出,这些四重不能从任何(3+1)维CFT导出.一个这样的例子是与Q^{111}上的圆锥相关联的规范理论。对于几个例子,我们明确确认晶体模型所建议的物质含量,超势相互作用和RG流。我们的研究结果提供了额外的支持的想法,晶体模型是相关的,用于描述这些CFTs的结构。

英文摘要:

We construct several examples of (2+1) dimensional N=2 supersymmetric Chern-Simons theories, whose moduli space is given by non-compact toric Calabi-Yau four-folds, which are not derivable from any (3+1) dimensional CFT. One such example is the gauge theory associated with the cone over Q^{111}. For several examples, we explicitly confirm the matter content, superpotential interactions and RG flows suggested by crystal models. Our results provide additional support to the idea that crystal models are relevant for describing the structure of these CFTs.
