在LHC和光子对撞机上Randall-Sundrum模型中的Radion

Radion in Randall-Sundrum model at the LHC and photon collider

Yoshiko Ohno

摘要:

由Randall和Sundrum(RS)提出的弯曲额外维模型是解决标准模型中规范层次问题的一个有吸引力的候选模型。在RS模型的最简单版本中,只有两个额外的粒子超出了标准模型-一个自旋为2的引力子(及其卡鲁扎-克莱因激发)和一个自旋为0且电中性的放射子。本文讨论了在光子对撞机上发现镭子的可能性,并将其作为$e^+ e^-$直线对撞机(ILC)的一个选择,重点讨论了镭子与光子或胶子相互作用的特征,以及在LHC上SM希格斯玻色子对镭子质量和耦合的限制。

英文摘要:

A warped extra dimension model proposed by Randall and Sundrum(RS) is one of the attractive candidates to solve the gauge hierarchy problem in the Standard Model. In a simplest version of the RS model, there are only two extra particles beyond the Standard Model - a spin-2 graviton (and its Kaluza-Klein excitations) and a radion which is a spin-0 and electrically neutral particle. In this paper, we discuss a possibility of discovering the radion at a photon collider, which has been considered as an option of $e^+ e^-$ liner collider (ILC), focusing on characteristic features of radion interactions with photon or gluon, in addition to constraints on mass and coupling of the radion from the SM Higgs boson search at the LHC.
