论文摘要
我们研究了各种参数集的晶格标准模型设置中物理量规不变状态的矢量 - 玻色子散射。为此,使用LüscherType分析确定标量通道中的相移。可以根据希格斯(Higgs)的特性和天生级别的弗里希尔·莫奇(Fröhlich-Morchio-Strocchi)分析来解释结果。唯一的偏差出现在弹性阈值以下的希格斯质量中,在那里我们发现负散射长度指示了物理标量自由度的结合状态。我们评估对效应的实验检测的可能影响。
We study vector-boson scattering of the physical, gauge-invariant states in a reduced standard-model setup on the lattice for various parameter sets. To this end, the phase shift in the scalar channel is determined using a Lüscher-type analysis. The results can be readily interpreted in terms of the Higgs properties and a reunitarized Fröhlich-Morchio-Strocchi analysis at Born level. The only deviation appears for a Higgs mass below the elastic threshold, where we find a negative scattering length indicative of the bound-state nature of the physical scalar degree of freedom. We assess the possible implications for an experimental detection of the effect.
