Stefan Antusch, Ilja Doršner, Kevin Hinze, Shaikh Saad

AI总结:

本文提出了一个基于$SU(5)$规范对称性和全局$U(1)$ Peccei-Quinn对称性的最小大统一理论模型,预测了质量在0.1至4.7 neV范围内的超轻轴子暗物质,并指出该模型的整个参数空间可通过多个低能实验的协同作用被完全测试。

摘要:

我们提出了一个最小大统一理论模型,基于$SU(5)$规范对称性和全局$U(1)$ Peccei-Quinn对称性,预测存在质量在狭窄范围$m_a\in[0.1,\\,4.7]\\,$neV内的超轻轴子暗物质。该质量窗口由规范耦合统一约束、部分质子衰变寿命限制以及重现实验观测到的费米子质量谱的需求共同决定。该模型的整个参数空间将通过寻找质子衰变的低能实验、通过轴子-光子耦合寻找轴子暗物质的实验(ABRACADABRA和DMRadio-GUT)以及寻找核子电偶极矩的实验(CASPEr Electric)的协同作用被探测。

英文摘要:

We present a minimal Grand Unified Theory model, based on $SU(5)$ gauge symmetry and a global $U(1)$ Peccei-Quinn symmetry, that predicts the existence of an ultralight axion dark matter within a narrow mass range of $m_a\in[0.1,\,4.7]\,$neV. This mass window is determined through an interplay between gauge coupling unification constraints, partial proton decay lifetime limits, and the need to reproduce the experimentally observed fermion mass spectrum. The entire parameter space of the proposed model will be probed through a synergy between several low-energy experiments that look for proton decay (Hyper-Kamiokande), axion dark matter through axion-photon coupling (ABRACADABRA and DMRadio-GUT) and nucleon electric dipole moments (CASPEr Electric).
