New Upper Limit of Terrestrial Equivalence Principle Test for Rotating Extended Bodies
arXiv:hep-ph/0303143 · doi:10.1103/PhysRevD.66.022002
Abstract
Improved terrestrial experiment to test the equivalence principle for rotating extended bodies is presented, and a new upper limit for the violation of the equivalence principle is obtained at the level of 1.6, which is limited by the friction of the rotating gyroscope. It means the spin-gravity interaction between the extended bodies has not been observed at this level.
