轻子生成、暗能量、暗物质和中微子

Leptogenesis, Dark Energy, Dark Matter and the neutrinos

Utpal Sarkar

摘要:

本文讨论了中微子质量模型对宇宙中物质-反物质不对称问题、暗能量或宇宙学常数问题以及暗物质候选者的解决方案。物质-反物质的不对称性可以用轻子生成来解释,轻子生成是由与中微子质量相关的轻子数破坏引起的。暗能量问题与质量变化的中微子有关,中微子可能起源于伪南布-戈德斯通玻色子。在某些中微子质量的辐射模型中,存在一个不获得真空期望值的希格斯偶线。这个场可能是惰性的,最轻的惰性粒子可能是暗物质的候选者。我们回顾了这些方案与模型的中微子质量右手中微子和三重态希格斯标量。

英文摘要:

In this review we discuss how the models of neutrino masses can accommodate solutions to the problem of matter-antimatter asymmetry in the universe, dark energy or cosmological constant problem and dark matter candidates. The matter-antimatter asymmetry is explained by leptogenesis, originating from the lepton number violation associated with the neutrino masses. The dark energy problem is correlated with a mass varying neutrinos, which could originate from a pseudo-Nambu-Goldstone boson. In some radiative models of neutrino masses, there exists a Higgs doublet that does not acquire any vacuum expectation value. This field could be inert and the lightest inert particle could then be a dark matter candidate. We reviewed these scenarios in connection with models of neutrino masses with right-handed neutrinos and with triplet Higgs scalars.
