摘要

我们研究了重单中微子在亲中子U(1)模型中作为暗物质（DM）候选者的前景，在这个模型中，标准模型（SM）被扩展为U(1)规对称，而中微子的质量和振荡参数则通过一种反锯机制来解释。最轻的重中微子扮演着DM的角色，而新引入的标量和额外的量规玻色子（Z'\）则充当暗部门和SM部门之间的中介。我们展示了在弱相互作用大质量粒子（WIMP）或微弱相互作用大质量粒子（FIMP）情景中可以容纳这种DM候选粒子的模型参数范围。在弱相互作用大质量粒子（WIMP）情景中，观测到的DM遗迹密度（DMRD）是通过新的规管玻色子和单子标量门户实现的；而在弱相互作用大质量粒子（FIMP）情景中，这两个粒子在产生观测到的DMRD中扮演了独特而关键的角色。

Heavy neutrino as dark matter in a neutrinophilic U(1) model

We study the prospect of heavy singlet neutrinos as a dark matter (DM) candidate within a neutrinophilic U(1) model, where the Standard Model (SM) is extended with a U(1) gauge symmetry, and neutrino mass and oscillation parameters are explained through an inverse see-saw mechanism. The lightest of the heavy neutrinos plays the role of the DM, while the newly introduced scalars and the extra gauge boson \(Z'\) act as mediators between the dark sector and the SM sector. We show the range of model parameters where this DM candidate can be accommodated in the Weakly Interacting Massive Particle (WIMP) or Feebly Interacting Massive Particle (FIMP) scenario. The observed DM relic density (DMRD) is achieved via the new gauge boson and singlet scalar portals in the WIMP scenario, whereas within the FIMP scenario, these two particles assume a distinct yet pivotal role in generating the observed DMRD.
