Search for $I^$ - $I^ˉ $ oscillation in $J / I ¨ \to I^ I^ˉ $ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +643

Using $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ decays collected by the BESIII detector at the BEPCII collider, we search for baryon number violation via $I^ - I^ˉ $ oscillation in the de…

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…
