Amplitude analysis and branching fraction measurement of the decay $D^0 \to K^+K^-π^0π^0$
BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres
An amplitude analysis of the singly Cabibbo-suppressed decay $D^0 \to K^+ K^- π^0 π^0$ is performed, for the first time, to determine the relative magnitudes and phases of different intermediate processes. The analysis uses $e^+e^-$ collision data collected with the BESIII detector …
