Abstract

The charmless three-body decays B(s)0→ KS0h+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→ KS0π+π−decay, and are determined to be: (Formula Presented.) at 90% confidencelevel, where fs/fdrepresents the ratio of hadronisation fractions of the Bs0and B0mesons.
