Improved search for two body muon decay μ+ → e+XH
Charged lepton flavor violating muon decay μ+ → e+XH, where XH is a massive neutral boson, was sought by searching for extra peaks in the muon decay μ+ → e+ν¯ν energy spectrum in the mXH mass region 47.8–95.1 MeV/c2. No signal was found and 90% confidence level upper limits were set on the branching...

No signal was found and 90% confidence level upper limits were set on the branching ratio Γ(μ+ → e+XH)/Γ(μ+ → e+ν¯ν) at the level of 10−5 for this region. |
