Measurement of the $D^0\to K^{-}\ddot{I}{€}^{+}{e}^{+}{e}^{-}$ branching fraction and search for $D^0\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}{e}^{+}{e}^{-}$ and $D^0\to K^{+}{K}^{-}{e}^{+}{e}^{-}$ decays at Belle

Belle, Belle II Collaborations, : +481

We present a study of the rare charm meson decays $D^0\to K^{+}{K}^{-}{e}^{+}{e}^{-}$, $\ddot{I}{€}^{+}\ddot{I}{€}^{-}{e}^{+}{e}^{-}$, and $K^{-}\ddot{I}{€}^{+}{e}^{+}{e}^{-}$ using a 942 fb${}^{-1}$ data se…
