标题： Constraints on Lorentz violation from clock-comparison experiments

摘要： 钟比较实验对洛伦兹和CPT对称性破坏的约束在标准模型的一般洛伦兹破坏扩展背景下被研究。实验信号显示取决于用作钟的原子和离子种类。某些通常被视为建立可比较限制的实验在此背景下对不同类型的洛伦兹破坏敏感。提出了与可能未来测量相关的某些考虑。所有这些实验都可能对普朗克尺度的洛伦兹破坏物理敏感。 显示英文摘要

摘要： Constraints from clock-comparison experiments on violations of Lorentz and CPT symmetry are investigated in the context of a general Lorentz-violating extension of the standard model. The experimental signals are shown to depend on the atomic and ionic species used as clocks. Certain experiments usually regarded as establishing comparable bounds are in this context sensitive to different types of Lorentz violation. Some considerations relevant to possible future measurements are presented. All these experiments are potentially sensitive to Lorentz-violating physics at the Planck scale.
