Abstract

A right-handed neutrino is a promising candidate for dark matter (DM) which has no interaction with nuclei. Since two right-handed neutrinos explain neutrino oscillation data and baryon number asymmetry through both the seesaw mechanism and leptogenesis based on the out-of-equilibrium decay of the lighter one, the lightest third right-handed neutrino could be free from them and stable to be DM. It suggests a possibility that the right-handed neutrinos could be common key particles for the explanation of three problems in the standard model (SM). We study this possibility by analyzing the structure of a neutrino mass matrix in the scotogenic model for neutrino mass.

右手中微子暗物质符合重子数不对称的产生

右手中微子是暗物质（DM）的一个有希望的候选者，它与原子核没有相互作用。由于两个右手中微子既可以通过跷跷板机制解释中微子振荡数据和重子数不对称，也可以通过基于较轻的一个的失平衡衰变的轻生作用来解释，因此最轻的第三个右手中微子可以不受它们的影响，并且稳定为DM。这表明右手中微子可能是解释标准模型（SM）中三个问题的共同关键粒子。我们通过分析中微子质量scotogenic模型中中微子质量矩阵的结构来研究这种可能性。
