论文摘要
轴和轴状颗粒的现象学在很大程度上取决于它们与标准模型颗粒的耦合。本文的重点是尊重移位对称性的独特维度六算子的现象学：轴轴 - higgs门户。我们比较了希格斯物理学的约束，违反风味和辐射的介子衰变，原子光谱范围的界限，以寻找第五力和天体物理可观察物。与QCD轴相反，通过轴突-Higgs门户相互作用的轴是稳定的，可以为任何轴质量提供暗物质候选。我们得出了冻结和冷冻生产以及未对准机制的参数空间，可以再现观察到的遗物丰度，并将结果与现象学约束进行比较。为了进行比较，我们还得出了希格斯，风味和光谱限制以及标量Higgs门户没有衍生相互作用的参数空间可以解释暗物质。
The phenomenology of axions and axion-like particles strongly depends on their couplings to Standard Model particles. The focus of this paper is the phenomenology of the unique dimension six operator respecting the shift symmetry: the axion-Higgs portal. We compare constraints from Higgs physics, flavor violating and radiative meson decays, bounds from atomic spectroscopy searching for fifth forces and astrophysical observables. In contrast to the QCD axion, axions interacting through the axion-Higgs portal are stable and can provide a dark matter candidate for any axion mass. We derive the parameter space for which freeze-out and freeze-in production as well as the misalignment mechanism can reproduce the observed relic abundance and compare the results with the phenomenological constraints. For comparison we also derive Higgs, flavor and spectroscopy constraints and the parameter space for which the scalar Higgs portal without derivative interactions can explain dark matter.
