Study of the $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} D_{s}^{+} D_{s}^{-}$ process from $s$ = 4.42 to 4.95 GeV at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +782

Based on $8.5 fb^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4.42 and 4.95 GeV with the BESIII detector at the BEPCII storage ring, we inves…
