Abstract

The prospects of tests of CPT symmetry using precision spectroscopy of antihydrogen are discussed with special emphasis on the ground-state hyperfine structure, a measurement of which is the aim of the ASACUSA collaboration at the AD/ELENA facility of CERN. Ongoing parallel experiments using hyperfine spectroscopy of hydrogen and deuterium aiming at studying Lorentz invariance by determining coefficients of the Standard Model Extension framework are described.

反氢、氢和氘的超精细光谱

摘要

讨论了使用反氢精密光谱测试 CPT 对称性的前景，特别强调了基态超精细结构，其测量是 ASACUSA 在 CERN 的 AD/ELENA 设施中合作的目标。描述了使用氢和氘的超精细光谱进行的平行实验，旨在通过确定标准模型扩展框架的系数来研究洛伦兹不变性。
