论文摘要
我们通过标量与四分之一相互作用作为充气的标量研究SM的最小扩展。对于仅在充气扇区中损坏比例对称性的模型,充气量的质量被限制为相对较低。在这里,我们分析了以前省略的流动量质量$m_χ\ gtrsim 250 \ text {gev} $。因此,由于其与希格斯部门的小混合,我们提供具有可行的通货膨胀特性的充气质量的窗口。与加拉顿相互作用引起的重型中性瘦素与Majorana质量诱发,使模型中的暗物质与质量$ o(1-10)\ text {mev} $。
We study the minimal extension of the SM by a scalar with quartic interaction serving as an inflaton. For the model where scale symmetry is broken only in the inflaton sector, the mass of the inflaton is constrained to be relatively low. Here, we analysed the previously omitted situation of the inflaton masses $m_χ\gtrsim 250\text{ GeV}$. Therefore, we provide a window of inflaton masses with viable inflationary properties that evade direct observational constraints, due to their small mixing with the Higgs sector. The addition of heavy neutral leptons with Majorana masses induced by the interaction with the inflaton allow for Cold Dark Matter in the model with masses $O(1-10)\text{ MeV}$.
