质子半径之谜的实验和理论研究现状

Review of experimental and theoretical status of the proton radius puzzle

Richard J. Hill

摘要:

测量到的μ介子氢的兰姆位移与电子-质子散射和常规氢光谱学的预期之间的差异被称为质子半径之谜,其最“平凡”的分辨率需要基本里德伯常量值的$> 5 σ$位移。我简要地回顾了光谱和散射测量的现状,最近的理论发展,以及对基础物理的影响。

英文摘要:

The discrepancy between the measured Lamb shift in muonic hydrogen and expectations from electron-proton scattering and regular hydrogen spectroscopy has become known as the proton radius puzzle, whose most "mundane" resolution requires a $> 5 σ$ shift in the value of the fundamental Rydberg constant. I briefly review the status of spectroscopic and scattering measurements, recent theoretical developments, and implications for fundamental physics.
