LHC II上的一个与翻转相关的单态

A Flippon Related Singlet at the LHC II

Tianjun Li, James A. Maxin, Van E. Mayes, Dimitri V. Nanopoulos

摘要:

我们考虑在${\cal F}$ - $SU(5)$模型中13 TeV LHC的750 GeV双光子共振,该模型具有标准模型(SM)单重场,耦合到TeV尺度的矢量类粒子,称为$flippons$。这个单态场扮演了750 GeV共振的角色,通过胶子融合产生,随后通过矢量粒子环衰变为双光子。我们提出了一个数值分析表明,所观察到的8 TeV和13 TeV的双光子生产截面可以产生在模型空间与现实的电荷和汤川耦合的光矢量类质量。我们进一步讨论了在一般无标度${\cal F}$ - $SU(5)$模型中光矢量质量的实验可行性,在这个一致的大统一理论中提供了一些基准场景,可以满足LHC和其他基本实验所施加的所有实验约束。

英文摘要:

We consider the 750 GeV diphoton resonance at the 13 TeV LHC in the ${\cal F}$-$SU(5)$ model with a Standard Model (SM) singlet field which couples to TeV-scale vector-like particles, dubbed $flippons$. This singlet field assumes the role of the 750 GeV resonance, with production via gluon fusion and subsequent decay to a diphoton via the vector-like particle loops. We present a numerical analysis showing that the observed 8 TeV and 13 TeV diphoton production cross-sections can be generated in the model space with realistic electric charges and Yukawa couplings for light vector-like masses. We further discuss the experimental viability of light vector-like masses in a General No-Scale ${\cal F}$-$SU(5)$ model, offering a few benchmark scenarios in this consistent GUT that can satisfy all experimental constraints imposed by the LHC and other essential experiments.
