Vincent Debierre, Christoph H. Keitel, Zoltan Harman

摘要:

提出了一种通过类氢离子的同位素位移谱来寻找假设的新相互作用的高效方法。的g因子和基态能量的加权差示出,以协助抑制有害的不确定性,从原子核结构,同时保持新的相互作用的假设的贡献。只需要来自单个同位素对的实验数据。考虑到的小,subleading核校正,允许表明,提供可行的实验进展是在UV/X射线光谱学,所提出的方法可以产生竞争力的新物理学电子耦合参数的界限相比,领先的界限从原子物理学提高了一个数量级以上。

英文摘要:

A highly effective approach to the search for hypothetical new interactions through isotope shift spectroscopy of hydrogen-like ions is presented. A weighted difference of the g factor and ground-state energy is shown to assist in the suppression of detrimental uncertainties from nuclear structure, while preserving the hypothetical contributions from new interactions. Experimental data from only a single isotope pair is required. Account is taken of the small, subleading nuclear corrections, allowing to show that, provided feasible experimental progress is achieved in UV/X-ray spectroscopy, the presented approach can yield competitive bounds on New Physics electron coupling parameters improved by more than an order of magnitude compared to leading bounds from atomic physics.
