F-理论和M-理论中局部模型的有效场论

Effective Field Theories for Local Models in F-Theory and M-Theory

Jacob L. Bourjaily

摘要:

要求可见扇形现象学有严格的局部起源,也许是人们能在高尺度上强加给弦论的最强、最可证伪的条件:它立刻排除了绝大多数弦景观,但却自然地导致了可以令人惊讶地现实(和熟悉)的构造。然而,只有在局部模型中,引力才能在保持规范耦合和汤川耦合强度不变的情况下变弱--这一限制是由低能实验很好地激发的。方便的是,可以从F-理论和M-理论的局部模型中产生的高尺度有效场论的整个类别都可以根据简单的纯群论规则进行分类。在这篇文章中,我们从一个对基本几何或高尺度物理不感兴趣的有效场论者的角度描述这些规则,并讨论这些模型对低能现象学的一般预测。

英文摘要:

Requiring a strictly local origin of visible sector phenomenology is perhaps the strongest, most falsifiable condition that one can impose on string theory at the high scale: it at once excludes a vast majority of the string landscape, and yet leads naturally to constructions that can be surprisingly realistic (and familiar). Yet only for local models can gravity be made parametrically weak while keeping the strength of gauge- and Yukawa-couplings fixed--a limit which is well-motivated by low-energy experiments. Conveniently, the entire class of high-scale effective field theories that can arise from such local models in F-theory and M-theory can be classified according to simple, purely group-theoretic rules. In this note, we describe these rules from the viewpoint of an effective field theorist with little interest in the underlying geometry or high-scale physics, and we discuss the general predictions these models have for low-energy phenomenology.
