论文摘要
在基于Orbifold紧凑型的一致自上而下的方法中，模块化和传统的风味对称性在非试图中与所谓的折衷风味对称性结合在一起。我们将此方案从前面讨论的两个额外维度扩展到字符串理论的六个额外维度。通过这样做，关于CP及其自发破坏的性质的新见解。此外，我们将R-对称性的新解释确定为与几何稳定的复杂结构模量相关的模块化对称性的不间断残余物。因此，所有对称性（即模块化，传统风味，CP和R）在字符串理论中具有共同的起源：在技术层面上，它们是由Narain太空组的外部自动形态给出的。折衷的自上而下的方法会带来一个非常限制的方案，并具有很高的预测能力。将其与现有的模块化风味对称性的自下而上结构联系起来仍然是一个挑战。
In a consistent top-down approach based on orbifold compactifications, modular and traditional flavor symmetries combine nontrivially to the so-called eclectic flavor symmetry. We extend this scheme from two extra dimensions, discussed previously, to the six extra dimensions of string theory. By doing so, new insights on the nature of CP and its spontaneous breaking emerge. Moreover, we identify a new interpretation of R-symmetries as unbroken remnants from modular symmetries that are associated with geometrically stabilized complex structure moduli. Hence, all symmetries (i.e. modular, traditional flavor, CP and R) share a common origin in string theory: on a technical level, they are given by outer automorphisms of the Narain space group. The eclectic top-down approach leads to a very restrictive scheme with high predictive power. It remains a challenge to connect this with existing bottom-up constructions of modular flavor symmetry.
