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^…

Unexpected large relative strong phase and search for isospin breaking and $C P$ asymmetries in $J/Ï\to K^*(892)\bar K

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

Using a direct scan of 26 energy points near the $J / I ¨ $ resonance, we perform the first measurement of the relative phase $I ¨ _{I^^{3}, 3 g}$ between the strong and electromagnetic ampli…
