论文摘要
在这项工作中，我们研究了带有紫外线（UV）和红外线（IR）的扭曲的五维（5D）模型，该模型用基本的5D Planck比例$ M $和曲率参数$ k $解决了层次结构问题，4D Planck Mass $ m_ _ _ { 10^{15} $ TEV。该模型在所有领域都表现出具有不同质量间隙的Kaluza-Klein（KK）模式的连续体。我们已经计算了绿色的功能和光谱密度，并显示了连续kk频谱的存在如何在某些标准模型过程的横截面中产生增强。该度量是在IR附近的线性，如线性dilaton和5D发条型模型，在同形坐标中是线性的，$ m \ sim $ tev。我们还分析了一个纯的（连续）线性DILATON场景，以$ M _ {\ textrm {planck}} $的更常规基本$ m $ $ m $和$ k $ scales解决层次结构问题，以及一个连续频谱。
In this work we study a warped five-dimensional (5D) model with ultraviolet (UV) and infrared (IR) branes, that solves the hierarchy problem with a fundamental 5D Planck scale $M$, and curvature parameter $k$, of the order of the 4D Planck mass $M_{\textrm{Planck}}\equiv 2.4\times 10^{15}$ TeV. The model exhibits a continuum of Kaluza-Klein (KK) modes with different mass gaps, at the TeV scale, for all fields. We have computed the Green's functions and spectral densities, and shown how the presence of a continuum KK spectrum can produce an enhancement in the cross section of some Standard Model processes. The metric is linear near the IR, in conformal coordinates, as in the linear dilaton and 5D clockwork models, for which $M\sim$ TeV. We also analyze a pure (continuum) linear dilaton scenario, solving the hierarchy problem with more conventional fundamental $M$ and $k$ scales of the order of $M_{\textrm{Planck}}$, and a continuum spectrum.
