论文摘要
收费的Lepton风味违反MUON衰减$μ^+{\ rightarrow} e^+x_h $，其中$ x_h $是一个巨大的中性玻色子，是通过在muon decay $μ^+{\ rightarrow} e^+rightarrow} e^+n^+bar bar的$ M________________ $ 47.8-95.1 $ MEV/$ C^2 $。未发现任何信号，并且在分支比率$γ（μ^+{\ rightArrow} e^+x_h）/γ（μ^+{\ rightArrow} e^+t \barν）$上设置了90％置信度上限。
Charged lepton flavor violating muon decay $μ^+{\rightarrow}e^+X_H$, where $X_H$ is a massive neutral boson, was sought by searching for extra peaks in the muon decay $μ^+{\rightarrow}e^+ν\barν$ energy spectrum in the $m_{X_H}$ mass region $47.8-95.1$ MeV/$c^2$. No signal was found and 90% confidence level upper limits were set on the branching ratio $Γ(μ^+{\rightarrow}e^+X_H)/Γ(μ^+{\rightarrow}e^+ν\barν)$ at the level of $10^{-5}$ for this region.
