标准模型Higgs衰变中的矢量玻色子极化

Vector boson polarizations in the decay of the Standard Model Higgs

Ezio Maina

摘要:

标准模型Higgs衰变到ZZ和WW时产生的轻子对的运动学分布与虚矢量玻色子的极化率有关。全振幅可以解析地分解成极化项的总和。几个观测量,特别是两个带电轻子的不变质量,一个来自每个玻色子,和轻子的角分布在矢量玻色子质心被证明是敏感的玻色子极化。

英文摘要:

The kinematic distributions of the lepton pairs produced in the decay of the Standard Model Higgs to ZZ and WW are related to the polarization fractions of the virtual vector bosons. The full amplitude can be decomposed analytically into a sum of polarized terms. Several observables, in particular the invariant mass of two charged leptons, one from each of the bosons, and the lepton angular distribution in the vector boson center of mass are shown to be sensitive to the boson polarizations.
