5D UED：扁平无味
5D UED: Flat and Flavorless
摘要：
5D UED不会自动最小程度地违反风味。这是由于膜上所需的味不对称反项。此外，有可能是更高维的运营商，直接有助于风味可观的。我们记录了一个大多不成功的尝试，利用本地化在一个平坦的额外的维度，以解决这些味道的限制，同时保持KK-奇偶校验作为一个良好的量子数。它是不成功的，因为我们似乎被迫以这样一种方式添加膜算子，以精确地模拟双喉弯曲额外维度的影响。在我们的努力过程中，我们遇到了一个问题，并提出了解决方案，共同的许多额外的维模型，其中领域是“双重本地化：”超轻模式。仔细研究后，这个问题似乎与维持卡鲁扎-克莱因宇称和通过局部化解决质量等级之间的内在紧张关系有关。
英文摘要：
5D UED is not automatically minimally flavor violating. This is due to flavor asymmetric counter-terms required on the branes. Additionally, there are likely to be higher dimensional operators which directly contribute to flavor observables. We document a mostly unsuccessful attempt at utilizing localization in a flat extra dimension to resolve these flavor constraints while maintaining KK-parity as a good quantum number. It is unsuccessful insofar as we seem to be forced to add brane operators in such a way as to precisely mimic the effects of a double throat warped extra dimension. In the course of our efforts, we encounter and present solutions to a problem common to many extra dimensional models in which fields are "doubly localized:" ultra-light modes. Under scrutiny, this issue seems tied to an intrinsic tension between maintaining Kaluza-Klein parity and resolving mass hierarchies via localization.
