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 ranging observations. We consider the pure gravitational sector and the classical point-mass limit in the matter sector of the minimal SME. We report no deviation from general relativity and put new realistic stringent constraints on LS violations improving up to 3 orders of magnitude previous estimations.

  1. Lorentz-violating matter-gravity couplings in small-eccentricity binary pulsars

    hep-ph 2019-08 accept novelty 6.0 of 10

    Using three small-eccentricity relativistic binary pulsars, this paper obtains order-of-magnitude upper limits on SME matter-gravity coefficients for neutrons, protons, and electrons.

  2. Modified gravitational wave propagations in linearized gravity with Lorentz and diffeomorphism violations and their gravitational wave constraints

    gr-qc 2025-01 conditional novelty 5.0 of 10

    No evidence of Lorentz or diffeomorphism violation is found in GWTC-3 gravitational waves, yielding 90% bounds on the lowest-dimension SME coefficients k(2)(I)00 and k(3)(V)jm.
