Measurement of the Branching Fraction of $\hat{I}{›}_c^{+}\to p{K}_S^0\ddot{I}{€}^0$ at Belle

The Belle, Belle II Collaborations, : +426

We report a precise measurement of the ratio of branching fractions $\mathcal{B}(\hat{I}{›}_c^{+}\to p{K}_S^0\ddot{I}{€}^0)/\mathcal{B}(\hat{I}{›}_c^{+}\to p{K}^{-}\ddot{I}{€}^{+})$ using 980 fb${}^{-1}$ of $e^{+}{e}^{-}$ data fro…
