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 μ=7.2×10^{-3} eV, and the self-coupling parameter λ≲105 is excluded at mass scale M=0.3 TeV. Especially, at the dark energy scale μ=2.4×10^{-3} eV, the constraint at M=1.3 TeV is improved by about 10 times the previous constraints on the torsion pendulum experiment.
利用对称子模型可以实现对高密度环境中标量场与物质之间耦合的动态筛选。提出了高精度短程引力实验来检验对称子模型。在这篇快报中，对华中科技大学2020年扭摆实验在亚毫米范围内检验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，华中科技大学2020年的实验对探测质量尺度为μ = 7.2×10⁻³ eV的对称子模型具有独特的敏感性，并且在质量尺度M = 0.3 TeV时排除了自耦合参数λ≲10⁵。特别是，在暗能量尺度μ = 2.4×10⁻³ eV时，在M = 1.3 TeV处的约束比之前扭摆实验的约束提高了约10倍。
