论文摘要
可以在标准模型扩展框架内系统地测试洛伦兹/CPT破裂的可能性。在纯重力部门中，质量尺寸5操作员在2体运动方程中产生了新的洛伦兹和CPT破裂的术语，这些运动取决于身体的相对速度。在这封信中，我们报告了使用月球激光范围的Lorentz/CPT侵略的15个独立中小型中小型中小企业系数的新约束。我们在1969年至2018年之间使用超过26,000个正常点对在SME框架内的月球范围内进行全球分析。我们还进行了折刀分析，以提供对系统不确定性的现实估计。没有报告与Lorentz/CPT对称性的偏差。另外，当同时适合洛伦兹/CPT抗衡的15个规范中小企业系数时，我们最多可以改善三个数量级的先前拟合后拟合后限制。
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.
