太阳系内引力对希格斯场的影响

Gravitational effects on the Higgs field within the Solar System

Franco D. Albareti, Antonio L. Maroto, Francisco Prada

摘要:

希格斯机制预言,除了一个新的标量玻色子的存在,存在一个恒定的希格斯场,弥漫在整个空间。该场的真空期望值(VEV)受到量子修正的影响,而量子修正主要是由希格斯场与规范玻色子和重夸克的自相互作用和耦合产生的。在这项工作中,我们表明,重力可以影响,在一个非平凡的方式,这些量子校正通过一个循环的贡献的有效势的有限部分。特别地,我们考虑了在缓慢变化的弱引力背景下由标准模型希格斯自相互作用产生的修正。所得到的结果相当于在希格斯VEV中存在不可忽略的不均匀性。这种不均匀性转化为粒子质量的空间变化,特别是质子与电子的质量比。我们发现太阳系中的这些希格斯粒子扰动是由爱丁顿参数控制的,而在纯广义相对论中是不存在的。然而,它们可能存在于修正的引力理论中。这种预测的效应可能会受到原子钟或高分辨率光谱测量的限制,这可能会改善目前对爱因斯坦引力修正的限制。

英文摘要:

The Higgs mechanism predicts, apart from the existence of a new scalar boson, the presence of a constant Higgs field that permeates all of space. The vacuum expectation value (VEV) of this field is affected by quantum corrections which are mainly generated by the self-interactions and couplings of the Higgs field to gauge bosons and heavy quarks. In this work we show that gravity can affect, in a non-trivial way, these quantum corrections through the finite parts of the one-loop contributions to the effective potential. In particular, we consider the corrections generated by the Standard Model Higgs self-interactions in slowly-varying weak gravitational backgrounds. The obtained results amount to the existence of non-negligible inhomogeneities in the Higgs VEV. Such inhomogeneities translate into spatial variations of the particle masses, and in particular of the proton-to-electron mass ratio. We find that these Higgs perturbations in our Solar System are controlled by the Eddington parameter, and are absent in pure General Relativity. Yet, they may be present in modified gravity theories. This predicted effect may be constrained by atomic clocks or high-resolution spectroscopic measurements, which could allow to improve current limits on modifications of Einstein's gravity.
