Improved search for two body muon decay
A. Aguilar-Arevalo, M. Aoki, M. Blecher +21
Charged lepton flavor violating muon decay , where is a massive neutral boson, was sought by searching for extra peaks in the muon decay $μ^+{\rightar…
Search for Heavy Neutrinos in Decay
A. Aguilar-Arevalo, M. Aoki, M. Blecher +21
Heavy neutrinos were sought in pion decays by examining the observed muon energy spectrum for extra peaks in addition to the expected peak for a massless ne…
Improved Search for Heavy Neutrinos and a Test of Lepton Universality in the Decay $π^+ \rightarrow \mbox{e}^+ ν$
R. E. Mischke, A. Aguilar-Arevalo, M. Aoki +21
Two results from the PIENU Experiment are presented reporting a test of lepton universality in pion decay and improved limits on heavy neutrinos coupling to positrons. The status o…
Improved Search for Heavy Neutrinos in the Decay
A. Aguilar-Arevalo, M. Aoki, M. Blecher +21
A search for massive neutrinos has been made in the decay . No evidence was found for extra peaks in the positron energy spectrum indicative of pion decays invo…
Improved measurement of the $π\rightarrow \mbox{e} ν$ branching ratio
A. Aguilar-Arevalo, M. Aoki, M. Blecher +23
A new measurement of the branching ratio, $R_{e/μ} =Γ(π^+ \rightarrow \mbox{e}^+ ν+ π^+ \rightarrow \mbox{e}^+ νγ)/ Γ(π^+ \rightarrow μ^+ ν+ π^+ \rightarrow μ^+ νγ)$, resulted in $…
Search for Massive Neutrinos in the Decay pi --> e nu
PIENU Collaboration, M. Aoki, M. Blecher +20
Evidence of massive neutrinos in the pi --> e nu decay spectrum was sought with the background pi --> mu --> e decay chain highly suppressed. Upper limits (90% C.L.) on the neutrin…

An apparatus to search for mirror dark matter via the invisible decay of orthopositronium in vacuum
A. Badertscher, A. Belov, P. Crivelli +9
Mirror matter is a possible dark matter candidate. It is predicted to exist if parity is an unbroken symmetry of the vacuum. The existence of the mirror matter, which in addition t…
