First measurements of the branching fractions for the decay modes $\hat{I}{ž}_c^0\to \hat{I}›\hat{I}\cdot$ and $\hat{I}{ž}_c^0\to \hat{I}›\hat{I}{\cdot }^{\prime }$ and search for the decay $\hat{I}{ž}_c^0\to \hat{I}›\ddot{I}{€}^0$ using Belle and Belle II data

Belle, Belle II Collaborations, : +321

Using data samples of 988.4 fb${}^{-1}$ and 427.9 fb${}^{-1}$ collected with the Belle and Belle II detectors, we present a study of the singly Cabibbo-suppressed decays $Ξ_c^{0} \to…
