带隙连续共振谱
On gapped continuum resonance spectra
摘要:
在这项工作中,我们研究了一个扭曲的五维(5D)模型与紫外(UV)和红外(IR)膜,解决了层次问题的基本5D普朗克尺度$M$,和曲率参数$k$的顺序的4D普朗克质量$M_{\textrm{Planck}}\equiv 2.4\times 10^{15}$ TeV。该模型表现出一个连续的卡鲁扎-克莱因(KK)模式与不同的质量差距,在TeV尺度,为所有领域。我们已经计算了格林函数和谱密度,并显示了连续KK谱的存在下,可以产生一些标准模型过程的横截面的增强。度规在IR附近是线性的,在共形坐标中,如在线性的光子和5D发条模型中,其中$M\sim$ TeV。我们还分析了一个纯粹的(连续)的线性矩阵的情况下,解决层次结构问题与更传统的基本$M$和$k$尺度的顺序$M_{\textrm{Planck}}$,和连续谱。
英文摘要:
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.
