Radiative production and decay

1990

We have studied the muon decay channel of the lepton with the presence of a photon in e+e- annihilation data at Ec.m.=29 GeV from the Mark II detector. Included in this study is the first direct measurement of radiative decay. We find the ratio of the measured branching fraction to the expected value from QED to be 1.03±0.42. © 1990 The American Physical Society.
