LHC上的小兰德尔-桑德拉姆模型

The Little Randall-Sundrum Model at the LHC

Hooman Davoudiasl

摘要:

我们提出了一个预测性的扭曲模型的味道,截止到紫外尺度O(10^3)TeV,称为“小兰德尔-桑德拉姆(LRS)”模型。该模型对应于RS场景的因子y \approx 6的体积截断,并且全息地对偶于颜色数大于y的动态。与单独的规范和风味动力学,一些不必要的贡献,精密电弱,Z b \bar b,和风味可观的LRS框架中被抑制,与相应的RS的情况相比。LRS截断导致干净的(金色的)双轻子LHC信号显著增强,增强量为O(y^3)。

英文摘要:

We present a predictive warped model of flavor, cut off at an ultraviolet scale O(10^3) TeV, called the "Little Randall-Sundrum (LRS)" model. This model corresponds to a volume-truncation, by a factor y \approx 6, of the RS scenario and is holographically dual to dynamics with number of colors larger by y. With separate gauge and flavor dynamics, several unwanted contributions to precision electroweak, Z b \bar b, and flavor observables are suppressed in the LRS framework, compared with the corresponding RS case. The LRS truncation leads to a significant enhancement of the clean (golden) di-lepton LHC signals, by O(y^3).
