标题： Upper Higgs boson mass bounds from a chirally invariant lattice Higgs-Yukawa model

摘要： 我们通过手征不变格点Higgs-Yukawa模型中的直接格点计算，在标准模型的Higgs-费米子扇区以相同的手征Yukawa耦合结构的方式，建立了依赖于截止参数的Higgs玻色子质量上限。正如从Higgs扇区的平凡性图像预期的那样，我们观察到随着截止参数$\Lambda$的增加，质量上限减小。此外，通过与纯$\Phi^4$-理论中的相应分析进行比较，探索了费米子对质量上限贡献的强度。 显示英文摘要

摘要： 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 $\Lambda$. Moreover, the strength of the fermionic contribution to the upper mass bound is explored by comparing to the corresponding analysis in the pure $\Phi^4$-theory.
