Abstract

The charmless three-body decays B(s) 0 → KS 0h+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 → KS 0π+π− decay, and are determined to be: (Formula Presented.) at 90% confidencelevel, where fs/fd represents the ratio of hadronisation fractions of the Bs 0 and B0 mesons. © 2017, The Author(s).
