F-理论中新的Orientifold弱耦合极限

New Orientifold Weak Coupling Limits in F-theory

Paolo Aluffi, Mboyo Esole

摘要:

我们提出了新的显式结构的弱耦合极限的F-理论推广森的建设椭圆纤维化,这是不必要的Weierstrass形式。这些新的结构允许一个优雅的推导出几个膜的配置,不发生在森的限制,或将需要复杂的几何调整或打破超对称的原始框架。我们的方法是流线型的,首先推导出一个简单的几何解释森的弱耦合极限。这导致了一种自然的方式来组织从半稳定到不稳定的奇异纤维的过渡方面的所有这些限制。这些结构为模型构建者提供了一个新的平台,因为它们扩大了F理论中可以构建的超对称构型的数量。我们提出了几个明确的例子E8,E7和E6椭圆纤维。

英文摘要:

We present new explicit constructions of weak coupling limits of F-theory generalizing Sen's construction to elliptic fibrations which are not necessary given in a Weierstrass form. These new constructions allow for an elegant derivation of several brane configurations that do not occur within the original framework of Sen's limit, or which would require complicated geometric tuning or break supersymmetry. Our approach is streamlined by first deriving a simple geometric interpretation of Sen's weak coupling limit. This leads to a natural way of organizing all such limits in terms of transitions from semistable to unstable singular fibers. These constructions provide a new playground for model builders as they enlarge the number of supersymmetric configurations that can be constructed in F-theory. We present several explicit examples for E8, E7 and E6 elliptic fibrations.
