摘要:

我们提出了新的约束洛仑兹对称性(LS)违反月球激光测距(LLR)。这些约束是在标准模型扩展(SME)框架中导出的,旨在参数化物理学所有部门中的任何LS偏差。我们将自己限制在两个部门,即最小SME的纯引力部门和引力-物质耦合。我们描述了所采用的方法,并比较我们的结果与以前的分析的理论依据。这项工作构成了第一个直接的实验测定的SME系数使用LLR测量。

英文摘要:

We present new constraints on Lorentz symmetry (LS) violations with lunar laser ranging (LLR). Those constraints are derived in the standard-model extension (SME) framework aiming at parameterizing any LS deviations in all sectors of physics. We restrict ourself to two sectors namely the pure gravitational sector of the minimal SME and the gravity-matter coupling. We describe the adopted method and compare our results to previous analysis based on theoretical grounds. This work constitutes the first direct experimental determination of the SME coefficients using LLR measurements.
