论文摘要
最近发现，将三胞胎希格斯引入标准模型可以提供可行的瘦素生成，以产生我们宇宙的巴里昂不对称性，但前提是通货膨胀是由三胞胎higgs和sm higgs的混合状态驱动的。在这项工作中，我们调查了满足该模型真空稳定性和扰动性的可行参数空间。我们发现，三胞胎希格斯的引入也可以改善希格斯真空不稳定性的问题。我们提出了两个代表性的参数区域，其中中微子质量的起源，宇宙的重子不对称以及通货膨胀可以解释，同时与真空稳定性和扰动性保持一致。
Recently it has been found that introducing a triplet Higgs to the standard model could provide a feasible leptogenesis to generate the baryon asymmetry of our universe, providing that the inflation is driven by the mixing state of the triplet Higgs and SM Higgs. In this work, we survey the viable parameter space satisfying the vacuum stability and perturbativity in this model. We find that the introduction of the triplet Higgs would also ameliorate the problem of the Higgs vacuum instability. We present two representative parameter regions where the origin of neutrino masses, baryon asymmetry of the universe as well as inflation can be explained while keeping consistent with the condition of vacuum stability and perturbativity.
