(2,0)离散超共形物质商三重的F-理论

F-theory on Quotient Threefolds with (2,0) Discrete Superconformal Matter

Lara B. Anderson, Antonella Grassi, James Gray, Paul-Konstantin Oehlmann

摘要:

我们探讨6维紧致F-理论展示(2,0)超共形理论耦合到重力,包括离散带电超共形物质。从具有阿贝尔规范场和超共形扇区的F理论几何开始,我们提供了打破$U(1)$规范对称性的希格斯跃迁的例子,在这个例子中,物质场也非平凡地耦合到(2,0)SCFT。在紧化背景下,这对应于连接两个定义在奇异基复曲面上的纤维卡-丘几何的几何过渡。具有非零Mordell-Weil秩的椭圆纤维Calabi-Yau三重可以连接到构造为Calabi-Yau商的光滑非单连通亏格一纤维几何。这些超圆锥形的过渡表现出多个纤维的余维2的基础上。

英文摘要:

We explore 6-dimensional compactifications of F-theory exhibiting (2,0) superconformal theories coupled to gravity that include discretely charged superconformal matter. Beginning with F-theory geometries with Abelian gauge fields and superconformal sectors, we provide examples of Higgsing transitions which break the $U(1)$ gauge symmetry to a discrete remnant in which the matter fields are also non-trivially coupled to a (2,0) SCFT. In the compactification background this corresponds to a geometric transition linking two fibered Calabi-Yau geometries defined over a singular base complex surface. An elliptically fibered Calabi-Yau threefold with non-zero Mordell-Weil rank can be connected to a smooth non-simply connected genus one fibered geometry constructed as a Calabi-Yau quotient. These hyperconifold transitions exhibit multiple fibers in co-dimension 2 over the base.
