| Description: |
Using data samples of and collected with the Belle and Belle II detectors, we present a study of the singly Cabibbo-suppressed decays , , and . We observe the decay and find evidence for the decay , with corresponding branching ratios determined to be and B ( Ξ c 0 → Λ η ′ ) / B ( Ξ c 0 → Ξ − π + ) = ( 2.48 ± 0.82 ± 0.12 ) % , respectively. We find no significant signal in the Ξ c 0 → Λ π 0 decay mode and set an upper limit at the 90% credibility level of B ( Ξ c 0 → Λ π 0 ) / B ( Ξ c 0 → Ξ − π + ) ... |
