Observation of J/ψ→3γ
Physical Review Letters 101:10 (2008)
Abstract:
We report the first observation of the decay J/ψ→3γ. The signal has a statistical significance of 6σ and corresponds to a branching fraction of B(J/ψ→3γ)=(1.2±0.3±0.2)×10-5, in which the errors are statistical and systematic, respectively. The measurement uses ψ(2S)→π+π-J/ψ events acquired with the CLEO-c detector operating at the CESR e+e- collider. © 2008 The American Physical Society.The death of massive stars - I.
