论文摘要
我们阐明了磁性质量效应对SphaLeron能量的磁性效应，这对于成功的电动性baryogenogeny所需的重子数量至关重要。发现SPHALERON能量会响应磁性质量而增加。作为一种应用，我们研究了两吉格斯 - 二键模型中磁性质量的sphaleron能量和电子eak相变。尽管磁性质量可以筛选仪表玻色子环，但它可以更有效地放宽BARYON数量保存标准，从而扩大了可杀害的区域。只要量规部门是标准模型共同的，我们的发现将在任何新的物理模型中都是普遍的。
We elucidate a magnetic mass effect on a sphaleron energy that is crucial for baryon number preservation needed for successful electroweak baryogenesis. It is found that the sphaleron energy increases in response to the magnetic mass. As an application, we study the sphaleron energy and electroweak phase transition with the magnetic mass in a two-Higgs-doublet model. Although the magnetic mass can screen the gauge boson loops, it relaxes a baryon number preservation criterion more effectively, broadening the baryogenesis-possible region. Our findings would be universal in any new physics models as long as the gauge sector is common to the standard model.
