摘要

在本文中，我们提供了一组基于Elko的量子场的厄米相互作用，考虑到最近关于奇异旋量的最一般形式和Wigner简并的研究成果。我们认为厄米性和重正化性是定义Elko-Higgs相互作用的导数作为暗耦合的合适候选者的标准。然后，通过宇宙学对暗物质丰度的约束和希格斯介子介导的电子-暗物质散射的限制来确定模型的自由参数。

On Wigner degeneracy in Elko theory: Hermiticity and dark matter

In this paper, we provide a set of Hermitian interactions for quantum fields based on Elko, considering the recent achievements concerning the most general form of singular spinors and Wigner degeneracy. We consider Hermiticity and renormalizability a criterion to define the derivative Elko–Higgs interaction as the suitable candidate for a dark coupling. Then, the free parameters of the model are fixed by cosmological constraints on the dark matter abundance and limits on the electron-dark matter scattering mediated by the Higgs.
