复杂混合暴胀中的轻子生成和再加热

Leptogenesis and Reheating in Complex Hybrid Inflation

Carlos Martinez Prieto, David Delepine, Luis Arturo Urena Lopez

摘要:

我们研究了在文献[1]中描述的混合暴胀阶段结束时,最初存储在复合(瀑布)标量场中的电荷向重子不对称性的转变。瀑布场与右手中微子耦合,也是它们的马约拉纳质量的原因。电荷最终通过右手中微子的衰变转移到标准模型的轻子上,而没有引入新的CP破坏相互作用。其他所需的过程,如暴胀子场的衰变和宇宙的再加热也进行了详细讨论。

英文摘要:

We study the transformation into a baryon asymmetry of a charge initially stored in a complex (waterfall) scalar field at the end of a hybrid inflation phase as described in Ref[1]. The waterfall field is coupled to right-handed neutrinos, and is also responsible for their Majorana masses. The charge is finally transferred to the leptons of the Standard Model through the decay of the right-handed neutrinos without introducing new CP violating interactions. Other needed processes, like the decay of the inflaton field and the reheating of the Universe are also discussed in detail.
