II型跷跷板模型中的电弱相变和引力波

Electroweak Phase Transition and Gravitational Waves in the Type-II Seesaw Model

Ruiyu Zhou, Ligong Bian, Yong Du

摘要:

第二类跷跷板模型是同时解释非零中微子质量和观察到的宇宙重子不对称性的一个可能的候选者。本文详细研究了该模型的相变模式和引力波的产生。我们发现一个强大的一阶电弱相变一般倾向于积极的希格斯门耦合和轻三重态低于$\sim550$ GeV。此外,我们发现在相变过程中产生的引力波产额将处于BBO灵敏度的边缘,可以通过Ultimate-DECIGO进一步检验。

英文摘要:

The type-II seesaw model is a possible candidate for simultaneously explaining non-vanishing neutrino masses and the observed baryon asymmetry of the Universe. In this work, we study in detail the pattern of phase transition and the gravitational wave production of this model. We find a strong first-order electroweak phase transition generically prefers positive Higgs portal couplings and a light triplet below $\sim550$ GeV. In addition, we find the gravitational wave yield generated during the phase transition would be at the edge of BBO sensitivity and could be further examined by Ultimate-DECIGO.
