中微子质量、DM和重子不对称性的TeV-scale模型

A TeV-scale model for neutrino mass, DM and baryon asymmetry

Mayumi Aoki, Shinya Kanemura, Osamu Seto

摘要:

本文讨论了一个能同时解释宇宙中中微子振荡、暗物质和重子不对称性的TeV物理模型。由于精确的$Z_2$对称性,在三圈水平上产生了微小的中微子质量,这也保证了暗物质候选者的稳定性。额外的希格斯双重态不仅对微小的中微子质量是必需的,而且对成功的电弱重子生成也是必需的。该模型提供了各种歧视性的预测,特别是在带电希格斯现象。

英文摘要:

We discuss a model which would explain neutrino oscillation, dark matter, and baryon asymmetry of the Universe simultaneously by the physics at TeV scales. Tiny neutrino masses are generated at the three loop level due to the exact $Z_2$ symmetry, by which the stability of the dark matter candidate is also guaranteed. The extra Higgs doublet is required not only for the tiny neutrino masses but also for successful electroweak baryogenesis. The model provides various discriminative predictions especially in charged Higgs phenomenology.
