希格斯玻色子衰变为重夸克和重轻子:高阶修正

Higgs boson decay into heavy quarks and heavy leptons: higher order corrections

Victor T. Kim

摘要:

本文简要地评述了标准模型希格斯玻色子在M_H <2MW时衰变为底夸克和τ轻子宽度的理论预言。考虑了高阶微扰QCD(直到α_s^4能级)和QED修正的影响。讨论了希格斯玻色子衰变为bb和τ + τ-的衰变宽度的不确定性。

英文摘要:

Theoretical predictions for the decay width of Standard Model Higgs boson into bottom quarks and tau-leptons, in the case when M_H< 2M_W, are briefly reviewed. The effects of higher order perturbative QCD (up to alpha_s^4-level) and QED corrections are considered. The uncertainties of the decay width of Higgs boson into bb and tau+tau- are discussed.
