Amplitude analysis and branching fraction measurement of the decay $D^{0} \to K_{S}^{0} I ¨ ^{0} I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +703

An amplitude analysis of the decay $D^{0} \to K_{S}^{0} I ¨ ^{0} I ¨ ^{0}$ is performed to determine the relative magnitudes and phases of different intermediate processes. The analysis uses $e^…

Search for an isoscalar partner of the $Z_{c} (3900)$ in $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} I^\cdot J / I ¨ $

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

Using a data sample corresponding to an integrated luminosity of 20.3 fb $^{- 1}$ collected at center-of-mass energies from 4.18 to 4.95 GeV with the BESIII detector, we observe the…
