Abstract

The charmless three-body decays B0 (s) → K0 S h +h 0− (where h (0) = π, K) are analysed using a sample of pp collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fb−1 . The branching fractions are measured relative to that of the B0 → K0 S π +π − decay, and are determined to be: B B0→ K0 SK±π ∓ B(B0→ K0 S π+π−) = 0.123 ± 0.009 (stat) ± 0.015 (syst), B B0→ K0 SK+K− B(B0→ K0 S π+π−) = 0.549 ± 0.018 (stat) ± 0.033 (syst), B B0 s → K0 S π +π − B(B0→ K0 S π+π−) = 0.191 ± 0.027 (stat) ± 0.031 (syst) ± 0.011 (fs/fd), B B0 s → K0 SK±π ∓ B(B0→ K0 S π+π−) = 1.70 ± 0.07 (stat) ± 0.11 (syst) ± 0.10 (fs/fd), B B0 s → K0 SK+K− B(B0→ K0 S π+π−) ∈ [0.008 − 0.051] at 90% confidence level, where fs/fd represents the ratio of hadronisation fractions of the B0 s and B0 mesons.
