The search for dynamically screening the coupling between the scalar field and matter in high-density environment is achievable with the symmetron model. The high-accuracy and short-range gravity experiment is proposed to test the symmetron model. In this Letter, the data of the HUST-2020 torsion pendulum experiment testing the inverse-square law at submillimeter range is analyzed to constrain the symmetron model. The results show that the HUST-2020 experiment is uniquely sensitive to probe the symmetron model with a mass scale of $\mu =7.2\times {10}^{-3}\mathrm{eV}$, and the self-coupling parameter $\lambda \lesssim 105$ is excluded at mass scale $M=0.3\mathrm{TeV}$. Especially, at the dark energy scale $\mu =2.4\times {10}^{-3}\mathrm{eV}$, the constraint at $M=1.3\mathrm{TeV}$ is improved by about 10 times the previous constraints on the torsion pendulum experiment.

用 HUST-2020 扭摆实验约束 Symmetron 模型

利用对称子模型可以实现动态筛选高密度环境中标量场与物质之间的耦合。提出高精度短程重力实验来检验对称子模型。在这封信中，对 HUST-2020 扭摆实验在亚毫米范围内测试平方反比定律的数据进行了分析，以约束对称子模型。结果表明，HUST-2020 实验对探测质量规模为$\mu =7.2\times {10}^{-3}\mathrm{电子伏特}$, 和自耦合参数$\lambda \lesssim 105$被大规模排除$米=0.3\mathrm{TeV}$. 尤其是在暗能量尺度上$\mu =2.4\times {10}^{-3}\mathrm{电子伏特}$，约束在$米=1.3\mathrm{TeV}$比之前对扭摆实验的约束提高了约 10 倍。
