论文摘要
我们将五个维度的线性dilaton背景中具有一般DILATON耦合的各种散装场视为发条模型的连续限制。我们表明，批量场的零模式的定位和KK频谱中的质量差距不仅取决于散装的diLaton耦合，还取决于散装费米的批量质量参数。量规耦合的普遍性和扰动性的一致性将Dilaton耦合限制在勃雷群（Brane）占地的物质场以及大量仪表玻色子上。在线性dilaton背景中构建发条标准模型（SM），我们为散装质量参数提供了必要条件，以解释SM费米子的质量层次结构和混合。我们可以引入一个相当大的扩展参数$ \ varepsilon = e^{ - \ frac {2} {3} kz_c} $，以实现夸克部门的逼真风味结构，而没有散装质量参数的微调，但以大量的5D Planck尺度进行了微调。另一方面，我们可以将较小的扩展参数用于Lepton块，以解决HIGGS质量参数的层次结构问题的解决方案。我们发现，巨大的Kaluza-Klein（KK）仪表玻色子和巨大的KK Gravitons分别对轻质和沉重的费米子进行了更强烈的恋爱，因此在LHC的这些KK模式的共振研究中有一种互补性。
We consider various bulk fields with general dilaton couplings in the linear dilaton background in five dimensions as the continuum limit of clockwork models. We show that the localization of the zero modes of bulk fields and the mass gap in the KK spectrum depend not only on the bulk dilaton coupling, but also on the bulk mass parameter in the case of a bulk fermion. The consistency from universality and perturbativity of gauge couplings constrain the dilaton couplings to the brane-localized matter fields as well as the bulk gauge bosons. Constructing the Clockwork Standard Model (SM) in the linear dilaton background, we provide the necessary conditions for the bulk mass parameters for explaining the mass hierarchy and mixing for the SM fermions. We can introduce a sizable expansion parameter $\varepsilon=e^{-\frac{2}{3} kz_c}$ for the realistic flavor structure in the quark sector without a fine-tuning in the bulk mass parameters, but at the expense of a large 5D Planck scale. On the other hand, we can use a smaller expansion parameter for lepton masses, in favor of the solution to the hierarchy problem of the Higgs mass parameter. We found that massive Kaluza-Klein (KK) gauge bosons and massive KK gravitons couple more strongly to light and heavy fermions, respectively, so there is a complementarity in the resonance researches for those KK modes at the LHC.
