论文摘要
我们提出了一个标准模型扩展名,即vish $ν$(变体 - 轴seesaw higgs $ν$ -trino),那是$ n _ {\ text {dw}} = 1 $变化其前代的变化,$ν$ dfsz型号。在考虑中微子群众,暗物质和宇宙的重子不对称的起源时,Vish $ν$继承了$ν$ dfsz的解释能力,而当然,解决了强大的$ cp $问题。在这两种模型中,Electroweak量表都自然地免受高seeSAW量表的保护,该量表被Peccei-Quinn(PQ)自发对称性破坏量表所识别。通过风味变体耦合结构,vish $ν$逃避了一个域墙问题,从而扩展了$ν$ dfsz的宇宙学范围,包括可行的通货膨胀时期。本文的主要重点是Vish $ν$的通货膨胀动态及其在辐射稳定意义上的自然性。我们发现,非最小重力耦合,通常由Vish $ν$标量场开发,自然支持一个可行的充气场,通常具有PQ标量和HIGGS组件。一个轴质量窗口[$40μ\ text {ev},\ sim 2 \ text {mev} $]可访问即将进行的搜索,结果在(p)重新加热阶段恢复了PQ对称的情况。
We propose a Standard Model extension, coined VISH$ν$ (Variant-axIon Seesaw Higgs $ν$-trino), that is an $N_{\text{DW}} = 1$ variation of its predecessor, the $ν$DFSZ model. In accounting for the origin of neutrino masses, dark matter and the baryon asymmetry of the universe, VISH$ν$ inherits the explanatory power of $ν$DFSZ while, of course, resolving the strong $CP$ problem. In both models, the electroweak scale is naturally protected from a high seesaw scale that is identified with the Peccei-Quinn (PQ) spontaneous symmetry breaking scale. Through a flavour variant coupling structure, VISH$ν$ evades a domain wall problem, extending the cosmological reach of the $ν$DFSZ to include a viable period of inflation. The primary focus of this paper is on the inflationary dynamics of VISH$ν$ and their naturalness in the sense of radiative stability. We find that non-minimal gravitational couplings, generically developed by the VISH$ν$ scalar fields, naturally support a viable inflaton field which typically has both a PQ scalar and Higgs component. An axion mass window [$40μ\text{eV}, \sim 2\text{meV}$] accessible to forthcoming searches, results for the case where PQ symmetry is restored during the (p)reheating phase.
