一个例外超对称标准模型的双光子过剩

The Diphoton Excess from an Exceptional Supersymmetric Standard Model

Wei Chao

摘要:

在本文中,我们解释了双光子过剩的不变质量M $\approx$ 750 GeV,声称在运行2大型强子对撞机的ATLAS和CMS的合作,作为一个标量单态在字符串启发异常超对称标准模型(ESSM)的信号。标量单线态可能在ESSM的$U(1)^\prime$规范对称性的自发破缺中起一定的作用,并在包含在$E_6$群基本表象中的奇异夸克和类希格斯超多重态的帮助下耦合到双光子和/或胶子对。该模型可能会在LHC上产生足够大的产生截面,但除了强耦合区外,几乎不能适应共振的宽宽度。

英文摘要:

In this paper we explain the diphoton excess in the invariant mass M $\approx$ 750 GeV , claimed by the ATLAS and CMS collaborations at the run-2 LHC, as the signal of a scalar singlet in a string inspired exceptional supersymmetric standard model (ESSM). The scalar singlet might play a rule in the spontaneous breaking of the $U(1)^\prime$ gauge symmetry of the ESSM and couples to diphoton and/or gluon pair with the help of exotic quarks and Higgs-like supermultiplets, which are contained in the fundamental representation of the $E_6$ group. The model might give rise to a large enough production cross section at the LHC but can hardly fit with the wide width of the resonance except in the strong couple regime.
