Observation of the radiative decay J/ψ→e+e-γ
Creators
Description
We report the first observation of the (radiative) decay J/ψ→e+e-γ. Our data are from an experiment in which J/ψ is formed in antiproton-proton annihilations. The observed rate is consistent with a QED calculation based on final state radiation. Our measurement gives a branching ratio for this mode of (8.8±1.3±0.4)x10-3 for γ energy>100 MeV. copyright 1996 The American Physical Society
