Evidence for the Direct Two-Photon Transition from $ψ (3686)$ to $J / ψ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +354

The two-photon transition $ψ (3686) \to γ γ J / ψ$ is studied in a sample of 106 million $ψ (3686)$ decays collected by the BESIII detector. The branching fraction is measured to be $(3.1\…
