摘要：

名为无标度${\cal F}$ - $SU(5)$的超引力模型是基于翻转的$SU$（5）大统一理论（GUT）和额外的TeV标度矢量类翻转子多重态，在LHC运行1期间在7-8 TeV进行了部分探测，尽管其大部分模型空间仍然可行，应该可以在运行2期间由13-14 TeV的LHC访问。该模型框架具有相当独特的能力，提供一个轻CP甚至希格斯玻色子质量的青睐124-126 GeV的窗口，同时保留可测试的光超对称性（SUSY）光谱。我们总结了无标度${\cal F}$ - $SU(5)$在13-14 TeV LHC的前景，并回顾了一个有前途的方法来区分其长链级联衰变签名。我们进一步表明，比例依赖的所有模型尺度后，统一的规范质量$M_{1/2}$最大限度地减少电弱微调，使$Z$ -玻色子质量$M_Z$被表示为一个明确的功能$M_{1/2}$，$M_Z^2 = M_Z^2 (M_{1/2}^2)$，与隐式依赖于一个无量纲的比例$c$的超对称希格斯混合参数$μ$和$M_{1/2}$。最后，我们阐明了最近的标量张量测量和无标度超引力宇宙学模型，模仿Starobinsky模型的通货膨胀之间的经验联系。

英文摘要：

The Supergravity model named No-Scale ${\cal F}$-$SU(5)$, which is based upon the flipped $SU$(5) Grand Unified Theory (GUT) with additional TeV-scale vector-like flippon multiplets, has been partially probed during the LHC Run 1 at 7-8 TeV, though the majority of its model space remains viable and should be accessible by the 13-14 TeV LHC during Run 2. The model framework possesses the rather unique capacity to provide a light CP-even Higgs boson mass in the favored 124-126 GeV window while simultaneously retaining a testably light supersymmetry (SUSY) spectrum. We summarize the outlook for No-Scale ${\cal F}$-$SU(5)$ at the 13-14 TeV LHC and review a promising methodology for the discrimination of its long-chain cascade decay signature. We further show that proportional dependence of all model scales upon the unified gaugino mass $M_{1/2}$ minimizes electroweak fine-tuning, allowing the $Z$-boson mass $M_Z$ to be expressed as an explicit function of $M_{1/2}$, $M_Z^2 = M_Z^2 (M_{1/2}^2)$, with implicit dependence upon a dimensionless ratio $c$ of the supersymmetric Higgs mixing parameter $μ$ and $M_{1/2}$. Finally, we elucidate an empirical connection between recent scalar tensor measurements and No-Scale Supergravity cosmological models that mimic the Starobinsky model of inflation.
