Search for the electromagnetic Dalitz decays $I ¨ _{c J} \to e^{+} e^{-} I ¨ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a data sample of $(2.712 \pm 0.014) \times 1 0^{9}$ $I ¨ (3686)$ events collected at $s = 3.686$ GeV by the BESIII detector, we search for the rare electromagnetic Dalitz dec…

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…
