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) \…

Measurement of the branching fraction of $D_{s}^{+} \to ℓ^{+} I^½_{ℓ}$ via $e^{+} e^{-} \to D_{s}^{+} D_{s}^{-}$

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

Based on $10.64 fb^{- 1}$ of $e^{+} e^{-}$ collision data taken at center-of-mass energies between 4.237 and 4.699 GeV with the BESIII detector, we study the leptonic $D_{s}^{+}$ de…
