摘要: We obtain improved constraints on the coupling constants of axion-like particles to nucleons from a recently performed Casimir-less experiment. For this purpose, differential force between Au-coated sphere and either Au or Si sectors rotating disc, arising due two-axion exchange, is calculated. Over wide region axion masses 1.7 meV 0.9 eV obtained are stronger up factor 60 than previously known ones following Cavendish-type experiment measurements effective Casimir pressure.
