标题： Neutrinos, vacuum stability and triple Higgs coupling in SMASH

摘要： 我们对SMASH（标准模型-轴子- seesaw -希格斯门户暴胀）框架的扩展标量部分的可观测后果进行现象学分析。 我们在SMASH标量参数空间的合适区域内解决了真空亚稳定性问题，并讨论了三重希格斯耦合$\lambda_{HHH}$的一环修正。 我们还发现，正确的中微子质量及质量平方差和宇宙的重子不对称性可由此模型产生，并考虑了该模型的Yukawa耦合的运行。 事实上，我们对该SMASH模型进行了完整的两环重整化群分析。 显示英文摘要

摘要： We perform a phenomenological analysis of the observable consequences on the extended scalar sector of the SMASH (Standard Model - Axion - Seesaw - Higgs portal inflation) framework. We solve the vacuum metastability problem in a suitable region of SMASH scalar parameter spaces and discuss the one-loop correction to triple Higgs coupling $\lambda_{HHH}$. We also find that the correct neutrino masses and mass squared differences and baryonic asymmetry of the universe can arise from this model and consider running of the Yukawa couplings of the model. In fact, we perform a full two-loop renormalization group analysis of the SMASH model.
