摘要:

超对称USp × USp规范理论给出了D3-膜探测$\mathbb{C}^2/\mathbb{Z}_2$上四个D 7-膜和一个O 7-平面的世界体积理论.我们证明,至少对于一个特定的选择在无穷远的完整性,我们可以去的规范理论的对偶描述,在那里我们可以添加一个费耶特-伊利奥普洛斯项描述的轨道爆破光滑ALE空间。这使得我们可以将光滑ALE空间上SO(8)瞬子的模空间表示为平坦空间乘以S类理论的希格斯分支的超凯勒商。我们还讨论了推广到$\mathbb{C}^2/\mathbb{Z}_{2n}$,并推测如何扩展分析更大的SO群和ALE空间的其他类型。

英文摘要:

The worldvolume theory of D3-branes probing four D7-branes and an O7-plane on $\mathbb{C}^2/\mathbb{Z}_2$ is given by a supersymmetric USp x USp gauge theory. We demonstrate that, at least for a particular choice of the holonomy at infinity, we can go to a dual description of the gauge theory, where we can add a Fayet-Iliopoulos term describing the blowing-up of the orbifold to the smooth ALE space. This allows us to express the moduli space of SO(8) instantons on the smooth ALE space as a hyperkähler quotient of a flat space times the Higgs branch of a class S theory. We also discuss a generalization to $\mathbb{C}^2/\mathbb{Z}_{2n}$, and speculate how to extend the analysis to bigger SO groups and to ALE spaces of other types.
