Study of the electromagnetic Dalitz decay $J / I ¨ \to e^{+} e^{-} I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

We report the first measurement of the di-electron invariant mass dependent transition form factor in the electromagnetic Dalitz decay $J / I ¨ \to e^{+} e^{-} I ¨ ^{0}$ using $(10087 \pm 44) \…

BESIII Collaboration, M. Ablikim, M. N. Achasov +653

By analyzing $(27.12 \pm 0.14) \times 1 0^{8}$ $I ¨ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decays of $Ï_{cJ} \to p \bar{p} K^0_S K^- Ï^+ +…
