论文摘要
我们考虑了一种基于Lepton数字侵入二次质量术语为非最低偶联通货膨胀模型的充气电位的模型。 $ l $ - 略大的质量项通过质量项Affleck-Dine机制在复杂的充气场中产生Lepton的不对称性，当Efflaton腐烂到右手（RH）中微子时，该机制将转移到标准模型（SM）扇区。该模型最小，因为它仅需要SM扇区，RH Neutrinos和非最少耦合的Eftraton扇区。我们发现，在公制通货膨胀中可以观察到Baryon等环境波动，但在Palatini膨胀中可以忽略不计。该模型与可以在可观察到的原始重力波中可检测到的重新加热温度兼容。
We consider a model of baryogenesis based on adding lepton number-violating quadratic mass terms to the inflaton potential of a non-minimally coupled inflation model. The $L$-violating mass terms generate a lepton asymmetry in a complex inflaton field via the mass term Affleck-Dine mechanism, which is transferred to the Standard Model (SM) sector when the inflaton decays to right-handed (RH) neutrinos. The model is minimal in that it requires only the SM sector, RH neutrinos, and a non-minimally coupled inflaton sector. We find that baryon isocurvature fluctuations can be observable in metric inflation but are negligible in Palatini inflation. The model is compatible with reheating temperatures that may be detectable in the observable primordial gravitational waves predicted by metric inflation.
