Observation of the electromagnetic doubly OZI-suppressed decay J/ψ → фπ0
Using a sample of 1.31 billion J/ψ events accumulated with the BESIII detector at the BEPCII collider, we report the observation of the decay J/ψ→ϕπ0, which is the first evidence for a doubly Okubo-Zweig-Iizuka suppressed electromagnetic J/ψ decay. A clear structure is observed in the K+K− mass spec...
