Abstract

The charmless three-body decays B0(s) → K0S h+h0− (where h(0) = π, K) areanalysed 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 tothat of the B0 → K0S π+π− decay, and are determined to be:BB0→ K0SK±π∓B(B0→ K0S π+π−)= 0.123 ± 0.009 (stat) ± 0.015 (syst),BB0→ K0SK+K−B(B0→ K0S π+π−)= 0.549 ± 0.018 (stat) ± 0.033 (syst),BB0s → K0S π+π−B(B0→ K0S π+π−)= 0.191 ± 0.027 (stat) ± 0.031 (syst) ± 0.011 (fs/fd),BB0s → K0SK±π∓B(B0→ K0S π+π−)= 1.70 ± 0.07 (stat) ± 0.11 (syst) ± 0.10 (fs/fd),BB0s → K0SK+K−B(B0→ K0S π+π−)∈ [0.008 − 0.051] at 90% confidence level,where fs/fd represents the ratio of hadronisation fractions of the B0s and B0 me
