摘要:

我们考虑了在支持N=1规范理论的轨道折叠六环面上磁化D9膜的局部相容系统。在这样的实现中,物质多重态来自于连接不同膜堆的“扭曲”弦。在六维紧致空间中引入E5膜(E5)导致了瞬子效应。例如,如果系统被设计为产生SQCD,那么单个E5膜可以解释ADS/TVY超势。我们讨论了微妙的相互作用,存在于E5边界的annuli图和N=1理论的有效低能量作用的全纯性质之间。这张照片的一致性允许获得的Kahler度量的手征物质多重线所产生的扭曲字符串的信息。

英文摘要:

We consider locally consistent systems of magnetized D9 branes on an orbifolded six-torus which support N=1 gauge theories. In such realizations, the matter multiplets arise from "twisted" strings connecting different stacks of branes. The introduction of Euclidean 5 branes (E5) wrapped on the six-dimensional compact space leads to instanton effects. For instance, if the system is engineered so as to yield SQCD, a single E5 brane may account for the ADS/TVY superpotential. We discuss the subtle interplay that exists between the annuli diagrams with an E5 boundary and the holomorphicity properties of the effective low-energy action of the N=1 theory. The consistency of this picture allows to obtain information on the Kahler metric of the chiral matter multiplets arising from twisted strings.
