摘要

我们介绍了在两个相反的外磁场方向上对两个基态氢超频跃迁进行的拉比式测量。这首次在水平上对标准模型扩展的一组系数施加了约束，而以前的实验并没有测量到这些系数。此外，我们还介绍了一种适用于光束中反氢超细光谱分析的新方法，它可以根据在相同磁场下测量到的两个跃迁来确定零场超细跃迁频率。我们的值为，与文献一致，相对精度为 0.44 ppb。这是在光束中对氢实现的最高精度，比以前的结果提高了 6 倍。

CPT and Lorentz symmetry tests with hydrogen using a novel in-beam hyperfine spectroscopy method applicable to antihydrogen experiments

We present a Rabi-type measurement of two ground-state hydrogen hyperfine transitions performed in two opposite external magnetic field directions. This puts first constraints at the level of

on a set of coefficients of the Standard Model Extension, which were not measured by previous experiments. Moreover, we introduce a novel method, applicable to antihydrogen hyperfine spectroscopy in a beam, that determines the zero-field hyperfine transition frequency from the two transitions measured at the same magnetic field. Our value,

, is in agreement with literature at a relative precision of 0.44 ppb. This is the highest precision achieved on hydrogen in a beam, improving over previous results by a factor of 6.
