存在轻SM Higgs时顶夸克质量的变化

Running Top quark mass in the presence of light SM Higgs

V. Sauli

摘要:

在Schwinger-Dyson方程的非微扰框架下考虑顶夸克质量的运动。该方法基于在Tevatron上测量的物理极质量输入,提供了在低类空和类时尺度下几乎为常数的质量函数。考虑了包括标准模型Higgs和胶子在内的骨架环。除了考虑顶夸克自能的单圈修饰近似外,还考虑了三重态Higgs相互作用的主要双圈骨架贡献。

英文摘要:

The running of the Top quark mass is considered in the nonperturbative framework of the Schwinger-Dyson equation. Based on the input of physical pole mass meassured at the Tevatron the method provides the resulting mass function which is almost constant at low spacelike and timelike scales. The skeleton loops including Standard Model Higgs and gluons are taken into account. The dominant two-loop skeleton contribution with triplet Higgs interaction is considered in addition to one loop dressed approximation of the top quark self-energy.
