跷跷板机制中的暴胀和majoron暗物质

Inflation and majoron dark matter in the seesaw mechanism

Sofiane M. Boucenna, Stefano Morisi, Qaisar Shafi, Jose W. F. Valle

摘要:

我们提出暴胀和暗物质有一个共同的起源,与中微子质量产生方案有关。作为一个模型,我们考虑了整体轻子数在跷跷板机制下的自发破缺。我们表明,它提供了一个可接受的通货膨胀的情况下,与最近的CMB B-模式观察的BICEP 2实验。该方案也可以通过合理的参数选择来解释宇宙的重子不对称性。

英文摘要:

We propose that inflation and dark matter have a common origin, connected to the neutrino mass generation scheme. As a model we consider spontaneous breaking of global lepton number within the seesaw mechanism. We show that it provides an acceptable inflationary scenario consistent with the recent CMB B-mode observation by the BICEP2 experiment. The scheme may also account for the baryon asymmetry of the Universe through leptogenesis for reasonable parameter choices.
