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:
B(B0→K0SK±π∓)B(B0→K0SK+π−)=0.123±0.009(stat)±0.015(syst),B(B0→K0SK+K−)B(B0→K0Sπ+π−)=0.549±0.018(stat)±0.033(syst),B(B0s→K0Sπ+π−)B(B0→K0Sπ+π−)=0.191±0.027(stat)±0.031(syst)±0.011(fs/fd),B(B0s→K0SK±π∓)B(B0→K0Sπ+π−)=1.70±0.07(stat)±0.11(syst)±0.10(fs/fd),B(B0s→K0SK+K−)B(B0→K0Sπ+π−)∈[0.008−0.051]at90%confidencelevel,

where fs/fd represents the ratio of hadronisation fractions of the Bs0 and B0 mesons.
