Abstract
The charmless three-body decays B 0( s) → K 0S h+h′ − (where h(′) = 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 → K 0S π+π− decay, and are determined to be:
where fs/fd represents the ratio of hadronisation fractions of the B 0 s and B0 mesons.
