摘要:

带有标准模型(SM)场在其中传播的扭曲额外维度的框架是SM的一个非常有动机的扩展,因为它可以解决SM的普朗克弱和味道层次问题。我们考虑在14和33 TeV的大型强子对撞机(LHC)的信号产生的直接生产的新粒子在这个框架中,即,Kaluza-Klein(KK)SM粒子的激发。我们重点研究自旋1(规范玻色子)和自旋2(引力子)的KK粒子及其衰变为顶/底夸克(味守恒)和W/Z和希格斯玻色子。为此,我们提出了两个基准,右手(RH)或LH顶夸克,分别被本地化非常接近TeV端的额外的维度。我们在14 TeV(300 fb $^-1$和3000 fb $^-1$)和33 TeV LHC上给出了一些新的结果。我们发现,这些粒子的发现前景是相当有希望的,特别是在高光度升级。

英文摘要:

The framework of a warped extra dimension with the Standard Model (SM) fields propagating in it is a very well-motivated extension of the SM since it can address both the Planck-weak and flavor hierarchy problems of the SM. We consider signals at the 14 and 33 TeV large hadron collider (LHC) resulting from the direct production of the new particles in this framework, i.e.,Kaluza-Klein (KK) excitations of the SM particles. We focus on spin-1 (gauge boson) and spin-2 (graviton) KK particles and their decays to top/bottom quarks (flavor-conserving) and W/Z and Higgs bosons, in particular. We propose two benchmarks for this purpose, with the right-handed (RH) or LH top quark, respectively, being localized very close to the TeV end of the extra dimension. We present some new results at the 14 TeV (with 300 fb$^-1$ and 3000 fb$^-1$) and 33 TeV LHC. We find that the prospects for discovery of these particles are quite promising, especially at the high-luminosity upgrade.
