论文摘要
我们提出了一种基于标准的I SeeSAW模型的瘦化机制，该机制成功地在右撇子中的质量中成功运行，低至几个100 TEV。我们将这种机制称为“洗涤液生成”，在中微子部门不需要任何CP违规，即使在强大的冲洗状态下也可以实施。洗涤液生成背后的关键思想是将标准的冻结生成概括为非最小化的宇宙学背景，在这种背景下，在瘦素生成温度下，所有颗粒在化学平衡中均不在化学平衡中的化学电位被允许采用任意值。这为建立了许多新的男生成模型的阶段设定了阶段，在高温下，在高温下重新加工了在低温下产生非易变的B-L不对称性。作为具体的例子，我们讨论了斧头通货膨胀后和大统一背景下的洗涤液生成。
We present a leptogenesis mechanism based on the standard type-I seesaw model that successfully operates at right-handed-neutrino masses as low as a few 100 TeV. This mechanism, which we dub "wash-in leptogenesis", does not require any CP violation in the neutrino sector and can be implemented even in the regime of strong wash-out. The key idea behind wash-in leptogenesis is to generalize standard freeze-out leptogenesis to a nonminimal cosmological background in which the chemical potentials of all particles not in chemical equilibrium at the temperature of leptogenesis are allowed to take arbitrary values. This sets the stage for building a plethora of new baryogenesis models where chemical potentials generated at high temperatures are reprocessed to generate a nonvanishing B-L asymmetry at low temperatures. As concrete examples, we discuss wash-in leptogenesis after axion inflation and in the context of grand unification.
