论文摘要
II型SEESAW模型是同时解释非季节性中微子肿块和观察到的宇宙的Baryon不对称性的候选者。在这项工作中，我们详细研究了该模型的相变模式和重力波的产生。我们发现一个强大的一阶电动相过渡通常更喜欢正式Higgs Portal耦合和低于$ \ sim550 $ GEV的轻单元。此外，我们发现相变期间产生的重力波产量将处于BBO敏感性的边缘，并且可以通过Ultimate-Decigo进一步检查。
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.
