Measurement of the Inclusive Cross Sections of Prompt $J / I ¨ $ and $I ¨ (3686)$ Production in $e^{+} e^{-}$ Annihilation from $s = 3.808$ to $4.951$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +610

The inclusive cross sections of prompt $J / I ¨ $ and $I ¨ (3686)$ production are measured at center-of-mass energies from 3.808 to 4.951 GeV. The dataset used is 22 fb $^{- 1}$ of $e^{+}e…

Precision measurement of the branching fraction of \boldmath $J / I ¨ \to K^{+} K^{-}$ via $I ¨ (2 S) \to I ¨ ^{+} I ¨ ^{-} J / I ¨ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using a sample of $448.1 \times 1 0^{6}$ $I ¨ (2 S)$ events collected with the BESIII detector, we perform a study of the decay $J / I ¨ \to K^{+} K^{-}$ via $Ï(2S)\rightarrow Ï^+Ï^-J/…
