摘要:

标准模型扩展(SME)是一个有效场论框架,旨在参数化物理学所有领域中对洛伦兹对称性(LS)的任何破坏。在这封信中,我们报告了第一次直接实验测量SME系数同时进行两个部门的SME框架内使用月球激光测距观测。我们考虑的纯引力部门和经典的点质量极限的物质部门的最小SME。我们报告没有偏离广义相对论,并提出了新的现实的严格限制LS违反提高了3个数量级以前的估计。

英文摘要:

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.
