Cédric Delaunay, Roee Ozeri, Gilad Perez, Yotam Soreq

摘要:

我们提出了一种新的方法来探测新的基本相互作用同位素位移光谱在原子钟跃迁。作为一个具体的玩具例子,我们把重点放在希格斯玻色子与物质的组成部分:电子和上下夸克的耦合上。我们表明,吸引力的希格斯力之间的核和它们的束缚电子,这是约束不良,可能会引起的影响,大于目前的实验灵敏度。更一般地说,我们讨论如何新的电子和中子之间的相互作用,介导通过光新的自由度,可能会导致可测量的非线性在国王图比较两个不同的过渡同位素位移。考虑到频率比较的最新精确度,同位素位移具有以亚Hz精确度测量的潜力,从而潜在地使得能够改进对新的基本相互作用的当前限制。这种测量的候选原子系统需要两个不同的时钟跃迁和四个零核自旋同位素。我们确定了几个系统,满足这一要求,并简要讨论现有的测量。我们考虑希格斯力相关的影响的大小和它产生可观察信号的要求。

英文摘要:

We propose a novel approach to probe new fundamental interactions using isotope shift spectroscopy in atomic clock transitions. As concrete toy example we focus on the Higgs boson couplings to the building blocks of matter: the electron and the up and down quarks. We show that the attractive Higgs force between nuclei and their bound electrons, that is poorly constrained, might induce effects that are larger than the current experimental sensitivities. More generically, we discuss how new interactions between the electron and the neutrons, mediated via light new degrees of freedom, may lead to measurable non-linearities in a King plot comparison between isotope shifts of two different transitions. Given state-of-the-art accuracy in frequency comparison, isotope shifts have the potential of being measured with sub-Hz accuracy, thus potentially enabling the improvement of current limits on new fundamental interactions. Candidate atomic system for this measurement require two different clock transitions and four zero nuclear spin isotopes. We identify several systems that satisfy this requirement and also briefly discuss existing measurements. We consider the size of the effect related to the Higgs force and the requirements for it to produce an observable signal.
