PEN experiment: a precise test of lepton universality
C. J. Glaser, D. Pocanic, L. P. Alonzi +26
With few open channels and uncomplicated theoretical description, charged pion decays are uniquely sensitive to certain standard model (SM) symmetries, the universality of weak fer…
PEN: a low energy test of lepton universality
D. Pocanic, L. P. Alonzi, V. A. Baranov +24
Allowed charged meson decays are characterized by simple dynamics, few available decay channels, mainly into leptons, and extremely well controlled radiative and loop correctio…
New studies of allowed pion and muon decays
D. Pocanic, A. Palladino, L. P. Alonzi +27
Building on the rare pion and muon decay results of the PIBETA experiment, the PEN collaboration has undertaken a precise measurement of B_{πe2} = R^π_{e/μ}, the π^+ -> e^+ν(γ) dec…

Using a large acceptance calorimeter and a stopped pion beam we have made a precise measurement of the rare Pi+ -> Pi0 e+ Nu,(pi_beta) decay branching ratio. We have evaluated the…
Increased Sensitivity to Possible Muonium to Antimuonium Conversion
V. Meyer, A. Grossmann, K. Jungmann +23
A new experimental search for muonium-antimuonium conversion was conducted at the Paul Scherrer Institute, Villigen, Switzerland. The preliminary analysis yielded one event fulfill…
