用反氢检验洛伦兹对称性

Tests of Lorentz symmetry using antihydrogen

Neil Russell

摘要:

CPT和洛伦兹破坏的信号在使用氢和反氢的光谱学的背景下是可能的。我们应用标准模型扩展,一个广泛的框架洛伦兹打破物理,各种过渡的氢和反氢光谱。结果表明,在这些系统的基态的上两个超精细子能级之间的过渡未抑制的效果。我们也讨论了潘宁陷阱中的相关实验,以及弯曲时空中洛伦兹破坏的最新工作。

英文摘要:

Signals of CPT and Lorentz violation are possible in the context of spectroscopy using hydrogen and antihydrogen. We apply the Standard-Model Extension, a broad framework for Lorentz breaking in physics, to various transitions in the hydrogen and antihydrogen spectra. The results show an unsuppressed effect in the transition between the upper two hyperfine sublevels of the ground state of these systems. We also discuss related tests in Penning traps, and recent work on Lorentz violation in curved spacetime.
