M理论五膜的超对称破缺

Supersymmetry Breaking Vacua from M Theory Fivebranes

Luca Mazzucato, Yaron Oz, Shimon Yankielowicz

摘要:

我们考虑实现N=2的超对称规范理论的相交膜组态被多迹超势破缺到N=1,并被软破缺到N=0。在M 5-膜包裹曲线的框架下,我们分析了超对称真空以及规范理论中自发超对称破缺和软超对称破缺的类比。我们证明了M5-膜不表现出亚稳态自发超对称破缺的模拟,也不具有具有全纯边界条件的非全纯最小体积曲线。然而,我们发现N=2的模空间中的任何点都可以旋转到一条非全纯的极小体积曲线上,其边界条件破坏了超对称性。我们把它们解释为规范理论中软超对称破缺真空的类似物。

英文摘要:

We consider intersecting brane configurations realizing N=2 supersymmetric gauge theories broken to N=1 by multitrace superpotentials, and softly to N=0. We analyze, in the framework of M5-brane wrapping a curve, the supersymmetric vacua and the analogs of spontaneous supersymmetry breaking and soft supersymmetry breaking in gauge theories. We show that the M5-brane does not exhibit the analog of metastable spontaneous supersymmetry breaking, and does not have non-holomorphic minimal volume curves with holomorphic boundary conditions. However, we find that any point in the N=2 moduli space can be rotated to a non-holomorphic minimal volume curve, whose boundary conditions break supersymmetry. We interpret these as the analogs of soft supersymmetry breaking vacua in the gauge theory.
