Updated branching fraction measurements of B (s)0 → K S0 h + h ′ − decays
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...
