LHC的自发时空约化和酉弱玻色子散射

Spontaneous Spacetime Reduction and Unitary Weak Boson Scattering at the LHC

Hong-Jian He, Zhong-Zhi Xianyu

摘要:

量子引力理论预言时空维度在高能量下会变小,这是一种引人注目的现象,被称为自发降维(SDR)。我们基于标准模型(SM)构建了一个有效的电弱理论,并引入了TeV尺度的SDR,该理论表现出良好的高能行为,并确保了弱规范玻色子散射的么正性。这也为标量希格斯玻色子存在时的层次问题提供了一个自然的解决方案。我们证明,该模型预测幺正纵向弱玻色子散射,并可以区分从传统的4d SM在欧洲核子研究中心的WW散射实验。

英文摘要:

Theories of quantum gravity predict spacetime dimensions to become reduced at high energies, a striking phenomenon known as spontaneous dimensional reduction (SDR). We construct an effective electroweak theory based on the standard model (SM) and incorporate the TeV-scale SDR, which exhibits good high energy behavior and ensures the unitarity of weak gauge boson scattering. This also provides a natural solution to the hierarchy problem in the presence of scalar Higgs boson. We demonstrate that this model predicts unitary longitudinal weak boson scattering, and can be discriminated from the conventional 4d SM by the WW scattering experiments at the CERN LHC.
