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^…
