Measurements of the branching fractions of ${\Lambda }_c^{+}\to \Lambda K^{+}{\pi }^0$ and ${\Lambda }_c^{+}\to \Lambda K^{+}\eta$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +400

We present a study of the three-body, singly Cabibbo-suppressed decays ${\Lambda }_c^{+}\to \Lambda K^{+}{\pi }^0$ and ${\Lambda }_c^{+}\to \Lambda K^{+}\eta$ using data recorded with the Belle and Belle II detectors at the…
