论文摘要
我们从类似氢的系统中计算出筛选的标量场理论的边界。新的轻标量字段通常具有直接的耦合。这种耦合受到无数实验测量的强烈限制。但是，某些理论具有{\ it筛选机制}，该筛选机构}允许这种耦合的效果动态削弱并逃避许多这样的界限。由于筛选的标量磁场，我们计算出对氢态系统的能量水平的扰动。然后，我们以两种方式使用此结果。首先，我们从氢光谱法计算边界，发现比筛查效应被忽略的情况明显弱的界限。其次，我们表明Muonium是筛选标量场的本质上更灵敏的探针。对于变色龙模型，Muonium实验探测了参数空间的很大一部分，该空间尚未被低能物理学探索，到目前为止仅通过高能量粒子物理学实验进行了测试。
We compute bounds on screened scalar field theories from hydrogen-like systems. New light scalar fields generically have a direct coupling to matter. Such a coupling is strongly constrained by myriad experimental measurements. However, certain theories possess a {\it screening mechanism} that allows the effects of this coupling to weaken dynamically, and to evade many such bounds. We compute the perturbations to the energy levels of hydrogen-like systems due to screened scalar fields. We then use this result in two ways. First, we compute bounds from hydrogen spectroscopy, finding significantly weaker bounds than have been reported before as screening effects were overlooked. Second, we show that muonium is an intrinsically much more sensitive probe of screened scalar fields. For chameleon models, muonium experiments probe a large part of the parameter space that is as yet unexplored by low energy physics and has so far only been tested by high-energy particle physics experiments.
