Аннотация:Results of the fit for the (left) Λ0b→(Λπ+)Λ+cπ− control mode and (right) Λπ+π− signal final states, for all subsamples combined. Superimposed on the data are the total result of the fit as a solid blue line, the Λ0b ( Ξ0b ) decay as a short-dashed black (double dot-dashed grey) line, cross-feed as triple dot-dashed brown lines, the combinatorial background as a long-dashed green line, and partially reconstructed background components with either a missing neutral pion as a dot-dashed purple line or a missing soft photon as a dotted cyan line.
