具有动力学重叠费米子的格点Higgs-Yukawa模型的希格斯玻色子玻色子质量上限和下限

Upper and lower Higgs boson mass bounds from a lattice Higgs-Yukawa model with dynamical overlap fermions

P. Gerhold, K. Jansen

摘要:

我们研究一个格点Higgs-Yukawa模型,它模拟了与电弱标准模型中Higgs扇区中相同的Higgs-fermion耦合结构,特别地,它服从一个Ginsparg-Wilson版本的SU(2)× U(1)对称性,由于忽略了该模型中的规范场,所以这里是一个整体对称性.在本文中,我们提出了我们的结果,截止依赖的上希格斯玻色子质量约束在几个选定的值的截止参数。

英文摘要:

We study a lattice Higgs-Yukawa model emulating the same Higgs-fermion coupling structure as in the Higgs sector of the electroweak Standard Model, in particular, obeying a Ginsparg-Wilson version of the underlying SU(2) x U(1) symmetry, being a global symmetry here due to the neglection of gauge fields in this model. In this paper we present our results on the cutoff-dependent upper Higgs boson mass bound at several selected values of the cutoff parameter.
