e+e-和光子对撞机上的双光子共振

Diphoton resonance at e+e- and photon colliders

F. Richard

摘要:

在这篇文章中,我将回顾在LHC观察到的新共振的暗示为未来的e+ e-TeV线性对撞机(LC)项目提供的机会。这一讨论主要受两种特定的物理场景的影响,这两种场景假设是(伪)标量共振或张量共振,但这些估计可以在大多数场景中使用。我设想一个光子对撞机,它有一个保证的信号与大型强子对撞机的观察,或一个标准的电子+电子对撞机,更直接的实施。在详细研究了重引力子的情况下,我得出结论,在TeV LC,高精度的测量,包括罕见的模式,允许明确地建立这种共振的起源。还详细设想了一个放射性粒子的情况,它说明了标量的产生。在兰德尔Sundrum模型的背景下,LC的希格斯粒子和顶部耦合的精确测量的作用被召回。

英文摘要:

In this note, I will review the opportunities offered by the hint of a new resonance observed at LHC for future e+e- TeV linear collider (LC) projects. This discussion is mainly influenced by two specific scenarios of physics which assume either a (pseudo-)scalar or a tensor resonance, but these estimates can be used in most scenarios. I envisage either a photon collider, which has a guaranteed signal with the LHC observation, or a standard e+e- collider, more straightforward to implement. After a detailed study of the heavy graviton scenario, I conclude that at a TeV LC, high accuracy measurements, including rare modes, allow to unambiguously establish the origin of this resonance. Also envisaged in some detail is a radion scenario which illustrates the production of a scalar. The role of an LC for precision measurements on Higgs and top couplings is recalled in the context of the Randall Sundrum model.
