论文摘要
他最近对$^4 $的观察表明，我们的宇宙具有大量的Lepton不对称性。我们考虑了Lepton数字生成的Affleck-Dine（AD）机制。在AD机制中，产生了称为L孔的非亲本孤子，并将生成的Lepton数限制在其中。 L球保护生成的Lepton编号免于通过SPHALERON过程转换为BARYON数字。我们研究了L球的形成和演变，并发现可以实现最近$^4 $ He测量所暗示的大量Lepton不对称的宇宙。
The recent observation of $^4$He implies that our universe has a large lepton asymmetry. We consider the Affleck-Dine (AD) mechanism for lepton number generation. In the AD mechanism, non-topological solitons called L-balls are produced, and the generated lepton number is confined in them. The L-balls protect the generated lepton number from being converted to baryon number through the sphaleron processes. We study the formation and evolution of the L-balls and find that the universe with large lepton asymmetry suggested by the recent $^4$He measurement can be realized.
