洛伦兹破坏的检验:通过月球Laser测距对标准模型扩展参数的约束

Testing for Lorentz Violation: Constraints on Standard-Model Extension Parameters via Lunar Laser Ranging

James B. R. Battat, John F. Chandler, Christopher W. Stubbs

摘要:

我们基于月球激光测距(LLR)数据提出了违反洛伦兹不变性的约束条件。LLR通过测量光在两个天体之间的往返行程来测量地月距离,目前精确到几厘米(总距离的$10^{11}$部分)。通过分析归档LLR数据下的标准模型扩展(SME)的框架,我们推导出六个观测约束的无量纲SME参数,描述潜在的洛伦兹破坏。我们没有发现这些参数在$10^{-6}$到$10^{-11}$水平上的洛伦兹破坏的证据。

英文摘要:

We present constraints on violations of Lorentz Invariance based on Lunar Laser Ranging (LLR) data. LLR measures the Earth-Moon separation by timing the round-trip travel of light between the two bodies, and is currently accurate to a few centimeters (parts in $10^{11}$ of the total distance). By analyzing archival LLR data under the Standard-Model Extension (SME) framework, we derived six observational constraints on dimensionless SME parameters that describe potential Lorentz-violation. We found no evidence for Lorentz violation at the $10^{-6}$ to $10^{-11}$ level in these parameters.
