论文摘要
希格斯耦合的精度测量首次直接探测费米昂质量产生的机理。这项工作的目的是确定这些测量值在多大程度上可以区分标准模型的树级机制和辐射质量产生的理论动机替代方案。为了关注第三户家庭,我们将最小的单环模型分类,并发现它们属于两个通用类别。通过详细探索几个基准模型,我们证明了tau-Lepton和底部夸克质量的辐射起源与当前的观察结果一致。尽管未来的对山着人将无法排除辐射起源,但它们可以探究有趣的参数空间区域。
Precision measurements of the Higgs couplings are, for the first time, directly probing the mechanism of fermion mass generation. The purpose of this work is to determine to what extent these measurements can distinguish between the tree-level mechanism of the Standard Model and the theoretically motivated alternative of radiative mass generation. Focusing on the third-family, we classify the minimal one-loop models and find that they fall into two general classes. By exploring several benchmark models in detail, we demonstrate that a radiative origin for the tau-lepton and bottom-quark masses is consistent with current observations. While future colliders will not be able to rule out a radiative origin, they can probe interesting regions of parameter space.
