Study of $\ddot{I}•\to K\bar{K}$ in the amplitude analysis of $D^{+}\to K_S^0{K}_L^0\ddot{I}{€}^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +772

We present the first amplitude analysis and branching fraction measurement of $D^{+}\to K_S^0{K}_L^0\ddot{I}{€}^{+}$ decay. The analysis uses a dataset corresponding to an in…
