The decay θ→η′ γ
A search for the process e+e-→θ(1020)→η′(958)γ in the decay channel η′→π+π-η, η→γγ was made in an experiment at the VEPP-2M e+e- collider with the SND detector. Analysis confirms the occurrence of θ→η′γ decay with probability B(θ→η′γ) = (6.7+3.4 -2.9) × 10-5. © 1999 American Institute of Physics.
