Freed Leptogenesis

Dmitry V. Zhuridov

摘要:

经济的扩展的标准模型(SM),其中著名的Davidson-Ibarra约束的CP不对称性相关的leptogenesis可能会显着放宽的环路效应,相比的预测SM扩展只有右手中微子与分级的质量,进行了讨论。这导致重中微子质量的下限减小,轻中微子质量的上限增大。此外,所考虑的理论可能有助于解决暗物质问题。

英文摘要:

Economical extensions of the Standard Model (SM), in which the famous Davidson-Ibarra bound on the CP asymmetry relevant for leptogenesis may be significantly relaxed by the loop effects, comparing to predictions of the SM extended only by right-handed neutrinos with hierarchical masses, are discussed. This leads to decreasing of the lower bound on the heavy neutrino masses and increasing of the upper bound on the light neutrino masses. In addition, the considered theory may help to solve the dark matter problem.
