洛伦兹/CPT破缺的可能性，这是由统一理论的动机，可以在标准模型的扩展框架内进行系统的测试。在纯重力部分，质量维5算子在2体运动方程中产生新的洛伦兹和CPT破缺项，这些项取决于物体的相对速度。在这封信中，我们报告了新的约束15个独立的SME系数洛伦兹/CPT违规与质量尺寸5使用月球激光测距。我们在SME框架内使用1969年至2018年期间的26，000多个正常点对月球测距数据进行了全球分析。我们还进行了刀切分析，以提供现实的估计系统的不确定性。没有偏离洛伦兹/CPT对称性的报告。此外，当同时拟合的15个典型的SME系数洛伦兹/CPT违规，我们提高了三个数量级以前的后拟合约束从无线电发射机。
The possibility for Lorentz/CPT-breaking, which is motivated by unification theories, can be systematically tested within the standard-model extension framework. In the pure gravity sector, the mass dimension 5 operators produce new Lorentz and CPT-breaking terms in the 2-body equations of motion that depend on the relative velocity of the bodies. In this Letter, we report new constraints on 15 independent SME coefficients for Lorentz/CPT-violations with mass dimension 5 using lunar laser ranging. We perform a global analysis of lunar ranging data within the SME framework using more than 26,000 normal points between 1969 and 2018. We also perform a jackknife analysis in order to provide realistic estimates of the systematic uncertainties. No deviation from Lorentz/CPT symmetries is reported. In addition, when fitting simultaneously for the 15 canonical SME coefficients for Lorentz/CPT-violations, we improve up to three orders of magnitude previous post-fit constraints from radio pulsars.
