我们建立了截止依赖的上希格斯玻色子质量约束的直接晶格计算的手征不变的晶格希格斯汤川模型的框架内模拟相同的手征汤川耦合结构中的希格斯费米子部门的标准模型。正如希格斯扇区的平凡性图所预期的那样,我们观察到上限质量随着截止参数Λ的增加而减少。此外,通过与纯Φ4-理论中相应的分析比较,探讨了费米子对上质量界贡献的强度。图1总结了我们关于截止依赖的希格斯玻色子质量上限的最终结果。
We establish the cutoff-dependent upper Higgs boson mass bound by means of direct lattice computations in the framework of a chirally invariant lattice Higgs-Yukawa model emulating the same chiral Yukawa coupling structure as in the Higgs-fermion sector of the Standard Model. As expected from the triviality picture of the Higgs sector, we observe the upper mass bound to decrease with rising cutoff parameter Λ. Moreover, the strength of the fermionic contribution to the upper mass bound is explored by comparing to the corresponding analysis in the pure Φ4-theory. Our final results on the cutoff-dependent upper Higgs boson mass bound are summarized in figure 1.
