轻子变味带电电流与相互作用

Lepton flavor changing charged current and interaction

Ong Jian Fuh, Ithnin Abdul Jalil

摘要:

我们把中微子质量本征态写在$SU(2)_L$群的弱偶线上。大质量中微子被写成味中微子的混合物。得到了轻子-W玻色子耦合的变味拉格朗日量。味中微子与带电轻子相互作用的顶角因子中出现了中微子混合角。这些结果导出了中微子在物质中振荡的费曼图,并在$(ν_e -e)$弹性散射中起重要作用。反常μ子衰变$μ^-\rightarrow e^-+\overlineν_μ+ν_e$参与给出了$2.197019 μs$ μ子衰变寿命。得到分支比$B(μ^-\rightarrow e^-+\overlineν_μ+ν_e)$。

英文摘要:

We write the neutrino mass eigenstate into the weak doublet of the group $SU(2)_L$ . The massive neutrino is written as the mixture of the flavor neutrino. The flavor changing Lagrangian of lepton-W boson coupling were obtained. The neutrino mixing angle appear in the vertex factor of the interaction of flavor neutrino with charged lepton. The results lead to the Feynman diagram of neutrino oscillation in matter and play an important role in $(ν_e -e)$ elastic scattering . The anomalous muon decay $μ^-\rightarrow e^-+\overlineν_μ+ν_e$ take part in giving the muon decay lifetime of $2.197019 μs$ . The branching ratio $B(μ^-\rightarrow e^-+\overlineν_μ+ν_e)$ is obtained.
