Measurement of the Branching Fraction of ${\Lambda }_c^{+}\to p{K}_S^0{\pi }^0$ at Belle

The Belle, Belle II Collaborations, : +426

We report a precise measurement of the ratio of branching fractions $\mathcal{B}({\Lambda }_c^{+}\to p{K}_S^0{\pi }^0)/\mathcal{B}({\Lambda }_c^{+}\to p{K}^{-}{\pi }^{+})$ using 980 fb${}^{-1}$ of $e^{+}{e}^{-}$ data from th…
