论文摘要
我们提出，如果他们的耦合在早期宇宙中具有较大的临时值，则可以通过$ \ sim 10 $ tev量表右撇子中微子进行弱的瘦素发生。如果光标量$ ϕ $由Fermions $ x $的热种群偏离其起源，在Electroweak Symmetry Breaking breaking oferweak $ x $中，则可以实现所需的提升参数。费米昂$ x $可以是可行的暗物质候选者；为了进行适当的参数选择，光标量本身可以通过未对准的机制为暗物质。我们发现，由$ x $和$ ϕ $组成的两个组件DM人口是我们框架中的典型结果。
We propose that weak scale leptogenesis via $\sim 10$ TeV scale right-handed neutrinos could be possible if their couplings had transitory larger values in the early Universe. The requisite lifted parameters can be attained if a light scalar $ϕ$ is displaced a long distance from its origin by the thermal population of fermions $X$ that become massive before electroweak symmetry breaking. The fermion $X$ can be a viable dark matter candidate; for suitable choice of parameters, the light scalar itself can be dark matter through a misalignment mechanism. We find that a two-component DM population made up of both $X$ and $ϕ$ is a typical outcome in our framework.
