$\mathcal{N} = (2,2)$超对称规范理论中的奇异BPS边界条件

Singular BPS boundary conditions in $\mathcal{N} = (2,2)$ supersymmetric gauge theories

Tadashi Okazaki, Douglas J. Smith

摘要:

本文导出了二维$\mathcal{N}=(2,2)$超对称规范理论中的一般BPS边界条件。我们分析这些边界条件的解决方案,特别是那些允许散装领域有极点的边界。我们还提出了在IIA型弦论中用膜表示的$\mathcal{N}=(2,2)$超对称规范理论的半BPS和四分之一BPS边界条件的膜组态。我们发现A-型和B-型膜结构都可以提升到M-理论,作为一个M2-膜系统,它终止于一个M5-膜,这个M5-膜包裹在$\mathbb{C}^2$中的一条全纯曲线与$\mathbb{C}^3$中一个特殊的拉格朗日3-圈的乘积上。

英文摘要:

We derive general BPS boundary conditions in two-dimensional $\mathcal{N}=(2,2)$ supersymmetric gauge theories. We analyze the solutions of these boundary conditions, and in particular those that allow the bulk fields to have poles at the boundary. We also present the brane configurations for the half- and quarter-BPS boundary conditions of the $\mathcal{N}=(2,2)$ supersymmetric gauge theories in terms of branes in Type IIA string theory. We find that both A-type and B-type brane configurations are lifted to M-theory as a system of M2-branes ending on an M5-brane wrapped on a product of a holomorphic curve in $\mathbb{C}^2$ with a special Lagrangian 3-cycle in $\mathbb{C}^3$.
