N=3 SCFT的N=1拉格朗日量

An N=1 Lagrangian for an N=3 SCFT

Gabi Zafrir

摘要:

我们提出,一定的$4d$ $\mathcal{N}=1$ $SU(2)\times SU(2)$规范理论在IR流到一个$\mathcal{N}=3$ SCFT加上一个单一的自由手征场。特定的$\mathcal{N}=3$ SCFT具有秩$1$和三维库仑分支算子。一般预期流降落在通过与所述库仑分支算子相关联的边缘变形而变形的$\mathcal{N}=3$ SCFT处。我们还提出了一个讨论各种RG不变量预期从$\mathcal{N}=3$超共形对称的属性,并使用这些来测试我们的建议。最后,我们讨论了对另一个$\mathcal{N}=1$模型的推广,我们提出该模型通过某些边缘变形的转向与某个秩$3$ $\mathcal{N}=3$ SCFT相关。

英文摘要:

We propose that a certain $4d$ $\mathcal{N}=1$ $SU(2)\times SU(2)$ gauge theory flows in the IR to an $\mathcal{N}=3$ SCFT plus a single free chiral field. The specific $\mathcal{N}=3$ SCFT has rank $1$ and a dimension three Coulomb branch operator. The flow is generically expected to land at the $\mathcal{N}=3$ SCFT deformed by the marginal deformation associated with said Coulomb branch operator. We also present a discussion about the properties expected of various RG invariant quantities from $\mathcal{N}=3$ superconformal symmetry, and use these to test our proposal. Finally, we discuss a generalization to another $\mathcal{N}=1$ model that we propose is related to a certain rank $3$ $\mathcal{N}=3$ SCFT through the turning of certain marginal deformations.
