AI Article Synopsis
- The symmetron model offers a way to dynamically screen the interaction between scalar fields and matter in dense environments.
- A new high-accuracy experiment called HUST-2020 aims to test this model by examining gravity's behavior at very short distances.
- Results from the HUST-2020 experiment indicate it can effectively narrow down parameters of the symmetron model, significantly improving constraints on dark energy scales compared to past experiments.
Article Abstract
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.
