论文摘要
我们提出了一个其他操作员的帮助，在希格斯膨胀中的自发瘦素发生：温伯格操作员（DIM 5）和希格斯场的衍生耦合和Lepton数字的电流（DIM 6）。前者是违反Lepton数量的原因，后者诱发了Lepton数字的化学潜力。在再加热期间，在希格斯膨胀中自然实现的迅速变化的希格斯场的时期允许Lepton数字中产生的不对称性大大增强，最终将其转化为宇宙的Baryon不对称。这种情况与希格斯通货膨胀模型的高加热温度兼容。
We propose a scenario of spontaneous leptogenesis in Higgs inflation with help from two additional operators: the Weinberg operator (Dim 5) and the derivative coupling of the Higgs field and the current of lepton number (Dim 6). The former is responsible for lepton number violation and the latter induces chemical potential for lepton number. The period of rapidly changing Higgs field, naturally realized in Higgs inflation during the reheating, allows large enhancement in the produced asymmetry in lepton number, which is eventually converted into baryon asymmetry of the universe. This scenario is compatible with high reheating temperature of Higgs inflation model.
