论文摘要
We investigate a scale-invariant $B-L$ scenario where the Standard Model (SM) is supplemented with a dark scalar $ϕ$ which has gauge \& Yukawa interactions, with the couplings $g_{BL}$ and $y$, respectively, leading to radiative plateau inflation at scale $ϕ=M$ in the ultraviolet (UV), while dynamically generating the Electroweak and Seesaw scales \ textit {ÁLá}在红外线（IR）中的Coleman-Weinberg。这是通过在能量尺度上实现阈值校正$μ_t$而尤其实现的，这是由于存在类似向量的费米子而产生的。我们表明，实施通货膨胀可观察物使耦合完全取决于高原尺度$ m $，仅给我们提供两个独立的参数$ m $ $ $和$μ_t$。在理论上一致的参数空间中，从$ m_ {z_ {bl}}> 850〜 \ rm GEV $，从从SM耦合中独立演变的黑暗扇区耦合的假设和$ <5.67〜m_p $实现了潜在的通货膨胀\ textiT型$ $ $ $ $ <5.67〜m_p $，$ <5.67〜m_p $ a plataighant \ textit plaplike there plaplike> plactike floplike there plaplike floplike ther $ m_p = 2.4 \ times10^{18} $ gev是减少的planck质量，我们确定了当前LHC排除的参数空间，而搜索了重$ z_ {bl} $ boson。对于可行参数区域中的典型基准点，我们估计加热温度为$ \ MATHCAL {O}（TEV）$，因此与标准的大爆炸核合成（BBN）约束是一致的。对于典型的基准点（$ m = 5.67，〜1，〜0.1〜m_p $），我们预测通货膨胀的范围为$ \ MATHCAL {H} _ {INF} = 2.79 \ times10^{12} $ GEV，$ 1.53 \ times10^\ times10^{10} $ GEV和$ 1.53 $ 1.53 $ gev，
We investigate a scale-invariant $B-L$ scenario where the Standard Model (SM) is supplemented with a dark scalar $ϕ$ which has gauge \& Yukawa interactions, with the couplings $g_{BL}$ and $y$, respectively, leading to radiative plateau inflation at scale $ϕ=M$ in the ultraviolet (UV), while dynamically generating the Electroweak and Seesaw scales \textit{á lá} Coleman-Weinberg in the infrared (IR). This is particularly achieved by implementing threshold corrections at an energy scale $μ_T$ arising due to the presence of vector-like fermions. We show that implementing the inflationary observables makes the couplings solely dependent on the plateau scale $M$, leaving us with only two independent parameters $M$ and $μ_T$. Within the theoretically consistent parameter space defined by $m_{Z_{BL}} > 850~\rm GeV$, from the assumption of independent evolution of the dark sector couplings from the SM couplings and $M < 5.67~M_P$ required for the realisation of inflationary \textit{plateau-like} behaviour of the potential around $ϕ=M$, where $M_P=2.4\times10^{18}$ GeV is the reduced Planck mass, we identify the parameter space that is excluded by the current LHC results from the search for the heavy $Z_{BL}$ boson. For typical benchmark points in the viable parameter regions, we estimate the reheating temperature to be $\mathcal{O}(TeV)$ thus consistent with the standard Big Bang Nucleosynthesis (BBN) constraints. For typical benchmark points ($M=5.67,~1,~0.1~M_P$) we predict the scales of inflation to be $\mathcal{H}_{inf}=2.79\times10^{12}$ GeV, $1.53\times10^{10}$ GeV and $1.53\times10^7$ GeV, respectively.
