论文摘要
在本文中，我们讨论了中微子现象学和相关宇宙学对$ a_ {4} \ otimes z_ {8} $ symmetric $ν$ 2hdm的影响，以及新粒子的添加，即仪表单元。附加粒子是无菌中微子，被认为是我们工作中可能的暗物质候选者。借助KEV范围内无菌中微子质量的选择，我们评估了考虑各种宇宙学限制的活性-DM混合角，衰减速率和遗物丰度。同时，还针对低尺度右中微子质量进行了关于男生生和中微子双β衰减的详细分析。我们考虑了从Lyman-$α$，X射线观察，Planck数据和Kamland-Zen限制等实验中的各种界限，以验证W.R.T模型中研究的现象。
In this paper, we discuss the impact of neutrino phenomenology and related cosmology on an $A_{4}\otimes Z_{8}$ symmetric $ν$2HDM along with an addition of a new particle, i.e. a gauge singlet(S). The additional particle is a sterile neutrino which is considered to be a probable dark matter candidate in our work. With the choice of sterile neutrino mass in keV range we evaluate the active-DM mixing angle, decay rate and relic abundance considering various cosmological constraints. Simultaneously, a detailed analysis on baryogenesis and neutrinoless double beta decay is also carried out for low scale right-handed neutrino masses. We have considered various bounds from experiments such as Lyman-$α$, X-ray observation, Planck data and KamLAND-Zen limit to validate the model w.r.t the phenomena studied in it.
