F理论激发的杂优弦导出模型中观测到的双光子过剩
The Observed Diphoton Excess in F-theory Inspired Heterotic String-Derived Model
摘要：
生产和随后的衰变的SM单线态通过重矢量样的颜色三重态和电弱双线在一个循环图可以揭示最近观察到的双光子过剩在大型强子对撞机。本文在F-理论下研究了$E_6$大统一理论，其中利用谱覆盖构造和超荷规范通量的作用，破缺了$E_6$.本文是根据\cite{Athanasopoulos:2014bba, Faraggi:2016xnm, Ashfaque:2016jha}中提出的结果，将简要回顾。在这里，按照F-理论的方法，类似于\cite{Karozas:2016hcp, Leontaris:2016wsy, Das:2016xuc}，我们提出了一个研究的翻转$SO(10)$模型完全嵌入在$E_{6}$大统一理论，但不同的住宿的SM表示${\bf{27}}$的$E_{6}$。
英文摘要：
The production and the subsequent decay of the SM singlet via heavy vector--like colour triplets and electroweak doublets in one--loop diagrams can shed light on the recent observation of diphoton excess at the LHC. In this paper, the $E_6$ GUT is considered in the F-theory setting where the $E_6$ is broken by making use of the spectral cover construction and by turning on the hypercharge gauge flux. This paper is based on the results presented in \cite{Athanasopoulos:2014bba, Faraggi:2016xnm, Ashfaque:2016jha} which will be reviewed briefly. Here, by following the F-theory approach, akin to \cite{Karozas:2016hcp, Leontaris:2016wsy, Das:2016xuc}, we present a study of the flipped $SO(10)$ model embedded completely in the $E_{6}$ GUT but with a different accommodation of the SM representations in the ${\bf{27}}$ of $E_{6}$.
