Lorentz Symmetry Violations from Matter-Gravity Couplings with Lunar Laser Ranging
Lorentz Symmetry Violations from Matter-Gravity Couplings with Lunar Laser Ranging
The standard-model extension (SME) is an effective field theory framework aiming at parametrizing any violation to the Lorentz symmetry (LS) in all sectors of physics. In this Letter, we report the first direct experimental measurement of SME coefficients performed simultaneously within two sectors of the SME framework using lunar laser …
