Sakura Schafer-Nameki, Timo Weigand

摘要:

在奇异的、椭圆纤维的卡-丘五重上紧化的F-理论产生了保持N=(0,2)超对称性的二维规范理论。在本文中,我们开始这样的紧化的研究,并确定字典之间的几何数据的椭圆纤维化和二维规范理论,如(0,2)超场和它们的超对称耦合的物质含量。我们研究这种设置都从规范理论的角度来看,在部分扭曲的7-膜理论,并提供了一个全球性的几何描述的基础上的结构的椭圆纤维化及其奇点。全局一致性条件的确定和检查对对偶M-理论紧化到一维。这包括对规范反常、格林-施瓦茨项的结构和对偶M理论超对称量子力学中的Chern-Simons耦合的讨论。此外,通过解释所得到的2d(0,2)理论作为杂种优势世界片理论,我们提出了一个对应的椭圆纤维Calabi-Yau五倍和目标空间的杂种优势规范线性σ模型(GLSM)的几何数据。特别地,2d(0,2)GLSM的Landau-Ginsburg相位和sigma模型相位之间的对应通过不同的T膜或F理论中的胶合数据来实现。

英文摘要:

F-theory compactified on singular, elliptically fibered Calabi-Yau five-folds gives rise to two-dimensional gauge theories preserving N=(0,2) supersymmetry. In this paper we initiate the study of such compactifications and determine the dictionary between the geometric data of the elliptic fibration and the 2d gauge theory such as the matter content in terms of (0,2) superfields and their supersymmetric couplings. We study this setup both from a gauge-theoretic point of view, in terms of the partially twisted 7-brane theory, and provide a global geometric description based on the structure of the elliptic fibration and its singularities. Global consistency conditions are determined and checked against the dual M-theory compactification to one dimension. This includes a discussion of gauge anomalies, the structure of the Green-Schwarz terms and the Chern-Simons couplings in the dual M-theory supersymmetric quantum mechanics. Furthermore, by interpreting the resulting 2d (0,2) theories as heterotic worldsheet theories, we propose a correspondence between the geometric data of elliptically fibered Calabi-Yau five-folds and the target space of a heterotic gauged linear sigma-model (GLSM). In particular the correspondence between the Landau-Ginsburg and sigma-model phase of a 2d (0,2) GLSM is realized via different T-branes or gluing data in F-theory.
