可见宇宙和暗宇宙的共同起源

Common Origin of Visible and Dark Universe

Pei-Hong Gu, Utpal Sarkar

摘要:

暗物质、重子物质和暗能量具有不同的性质,但对目前宇宙的能量密度贡献相当。我们指出,它们可能有一个共同的起源。由于暗能量的尺度远低于粒子物理学中已知的所有尺度,但非常接近中微子质量,而重子区中物质相对于反物质的过剩可能与中微子质量的产生有关,我们将暗宇宙和可见宇宙的起源统一在一个不同的跷跷板模型中.在我们的模型中,(i)暗物质残余密度是一种暗物质不对称性,它与轻子生成的重子不对称性同时出现;(ii)暗能量是由于与中微子质量生成有关的伪Nambu-Goldstone-玻色子。

英文摘要:

Dark matter, baryonic matter and dark energy have different properties but contribute comparable energy density to the present Universe. We point out that they may have a common origin. As the dark energy has a scale far lower than all known scales in particle physics but very close to neutrino masses, while the excess matter over antimatter in the baryonic sector is probably related to the neutrino mass-generation, we unify the origin of dark and visible Universe in a variant of seesaw model. In our model (i) the dark matter relic density is a dark matter asymmetry emerged simultaneously with the baryon asymmetry from leptogenesis; (ii) the dark energy is due to a pseudo-Nambu-Goldstone-Boson associated with the neutrino mass-generation.
