中微子质量、暗物质和重子不对称性的TeV标度模型

A TeV scale model for neutrino mass, dark matter and baryon asymmetry

Mayumi Aoki, Shinya Kanemura, Osamu Seto

摘要:

我们讨论了一个TeV尺度模型,该模型可以用扩展的Higgs扇形和TeV尺度右手中微子的动力学同时解释宇宙中的中微子振荡、暗物质和重子不对称性,并给出了精确的$Z_2$对称性.在三圈能级上产生了微小的中微子质量,单重态标量场是暗物质的候选者,并且实现了一个强的一级相变以实现成功的电弱重子生成。该模型提供了各种判别预测,使其在当前和未来的实验是可测试的。

英文摘要:

We discuss a TeV scale model which would explain neutrino oscillation, dark matter, and baryon asymmetry of the Universe simultaneously by the dynamics of the extended Higgs sector and TeV-scale right-handed neutrinos with imposed an exact $Z_2$ symmetry. Tiny neutrino masses are generated at the three loop level, a singlet scalar field is a candidate of dark matter, and a strong first order phase transition is realized for successful electroweak baryogenesis. The model provides various discriminative predictions, so that it is testable at the current and future experiments.
