论文摘要

从最小的超对称(SUSY)标准模型(MSSM)中的kev尺度重力武器是一种有趣的可能性,因为$λ$ cdm模型在现代宇宙学中遇到的小规模问题可以通过kev规模的gravitino来缓解,因为kev规模的graveritino作为温暖的暗物质(WDM)。这样的轻度重力要求低尺度的超对称性(SUSY)破裂,该仪表调解(GM)被要求作为一致的SUSY破坏调解机制。在本文中,我们展示了第二次CP-even Higgs Boson $ h $和CP-ODD HIGGS玻色子$ A $的上行,假设Kev-Scale Gravitino负责当前的DM Relic丰度:$ H/a $ a $ h/a $ h/sim a $ \ sim 4 $ \ sim a $ \ sim a 4 $ tev a $ te $ \ sim a $ \ sim a 4 $ tev。 $ \ MATHCAL {O}(10 $ - $ 100)$ KEV。有趣的是,$ h/a $的质量可能很小至2-3 tev,而预测的$ \tanβ$对于$ \ Mathcal {o}(10)$ kev的Gravitino Mass的质量为55-60。这将在不久的将来的大型强子对撞机(LHC)实验中进行测试。

A keV-scale gravitino arsing from a minimal supersymmetric (SUSY) Standard Model (MSSM) is an interesting possibility since the small scale problems that $Λ$CDM model encounters in the modern cosmology could be alleviated with the keV-scale gravitino serving as the warm dark matter (WDM). Such a light gravitino asks for a low scale supersymmetry (SUSY) breaking for which the gauge mediation (GM) is required as a consistent SUSY-breaking mediation mechanism. In this paper, we show upperbounds of the masses of the second CP-even Higgs boson $H$ and the CP-odd Higgs boson $A$, assuming the keV-scale gravitino to be responsible for the current DM relic abundance: the upperbound on the mass of $H/A$ is found to be $\sim 4$ TeV for the gravitino mass of $\mathcal{O}(10$-$100)$ keV. Interestingly, the mass of $H/A$ can be as small as 2-3 TeV and the predicted $\tanβ$ is as large as 55-60 for the gravitino mass of $\mathcal{O}(10)$ keV. This will be tested in the near future Large Hadron Collider (LHC) experiments.
