中微子质量、暗物质和重子不对称性的扩展希格斯扇区

An extended Higgs sector for neutrino mass, dark matter and baryon asymmetry

Mayumi Aoki, Shinya Kanemura, Osamu Seto

摘要:

在这次演讲中,我们讨论了TeV尺度模型,该模型将通过扩展希格斯扇区和TeV尺度右手中微子的动力学同时解释中微子振荡,暗物质和重子不对称性。通过施加精确的$Z_2$对称性,在三圈水平上产生微小的中微子质量,并保证了暗物质候选者的稳定性,即额外的单重标量场。额外的Higgs双重态的引入不仅是为了中微子的质量,也是为了成功的电弱重子生成。该模型提供了希格斯现象学中的各种判别性预测,这些预测可以在大型强子对撞机和国际线性对撞机上进行测试。

英文摘要:

In this talk, 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. By the imposed exact $Z_2$ symmetry, tiny neutrino masses are generated at the three loop level, and the stability of the dark matter candidate, an additional singlet scalar field, is guaranteed. The extra Higgs doublet is introduced not only for neutrino masses but also for successful electroweak baryogenesis. The model provides various discriminative predictions in Higgs phenomenology, which can be tested at the Large Hadron Collider and the International Linear Collider.
