First energy scan measurement of $e^{+} e^{-} \to K^{+} K^{-}$ around the $I ¨ (2 S)$ resonance

BESIII Collaboration, M. Ablikim, M. N. Achasov +684

We report the precise energy scan measurement of the cross section lineshape of $I ¨ (2 S) \to K^{+} K^{-}$ . The analysis is based on $e^{+} e^{-}$ collision data corresponding to an int…

Measurement of the branching fraction of $I^\cdot \to I^¼^{+} I^¼^{-}$ and search for $I^\cdot \to e^{+} e^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +702

We analyze the decay of $I^\cdot \to ℓ^{+} ℓ^{-} (ℓ = e, I^¼)$ via $J / I ¨ \to I^^{3} I^\cdot^{'}$ and $I^\cdot^{'} \to I ¨ ^{+} I ¨ ^{-} I^\cdot$ , based on (10087 $\pm$ 44) $\times$ 10 $^{6}$ $J / I ¨ $ event…

The Production and Decay Dynamics of the Charmed Baryon $I^_{c}^{+}$ in $e^{+} e^{-}$ Annihilations near Threshold

BESIII Collaboration, M. Ablikim, M. N. Achasov +700

The study of the charmed baryons is crucial for investigating the strong and weak interactions in the Standard Model and for gaining insights into the internal structure of baryons…

Evidence for the semileptonic decays $I^_{c}^{+} \to I^£^{\pm} I ¨ ^{\mp} e^{+} I^½_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +680

Using $4.5 f b^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector at center-of-mass energies between $4.600$ and $4.699 G e V$ , we search for the semileptonic decays…
