Torsion Balance Experiments Enable Direct Detection of Sub-eV Dark Matter

Posted by dbos Tokyo

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shigeki Matsumoto, Jie Sheng, Chuan-Yang Xing, Lin Zhu, | Summary: Light dark matter with sub-eV masses has a high number density in our galaxy, and its scattering cross section with macroscopic objects can be significantly enhanced by coherence effects. Repeated scattering with a target object can induce […]
