五膜的模网与超势

Moduli Webs and Superpotentials for Five-Branes

Marco Baumgartl, Simon Wood

摘要:

我们研究了单参数卡-丘模型,并确定了与嵌入这些流形中的线相关的D5-膜族。模空间由黎曼曲线的集合给出,这些黎曼曲线形成一个网,其交点由置换膜描述。我们到达一个几何解释的体积边界的全纯微分的模空间,并使用它来计算有效的开闭超势的开弦耦合的所有订单。确定了体变形下D5膜模量的不动点。

英文摘要:

We investigate the one-parameter Calabi-Yau models and identify families of D5-branes which are associated to lines embedded in these manifolds. The moduli spaces are given by sets of Riemann curves, which form a web whose intersection points are described by permutation branes. We arrive at a geometric interpretation for bulk-boundary correlators as holomorphic differentials on the moduli space and use this to compute effective open-closed superpotentials to all orders in the open string couplings. The fixed points of D5-brane moduli under bulk deformations are determined.
