Abstract

The charmless three-body decays B_(s) ⁰ → K_S 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 → K_S ⁰π⁺π⁻ decay, and are determined to be: (Formula Presented.) at 90% confidencelevel, where f_s/f_d represents the ratio of hadronisation fractions of the B_s ⁰ and B⁰ mesons.
