Sažetak
After a decade of no measurements of pion and muon rare decays, PIBETA, a new experimental program is producing its first results. We report on a new experimental study of the pion beta decay, π+→π0e+ν, the πe2γ radiative decay, π+→e+νγ, and muon radiative decay, . The new results represent four- to six-fold improvements in precision over the previous measurements. Excellent agreement with Standard Model predictions is observed in all channels except for one kinematic region of the πe2γ radiative decay involving energetic photons and lower-energy positrons.
