Study of light-meson resonances decaying to K S0 Kπ in the B → (K S0 Kπ)K channels

A study is presented of B+→KS0K-π+K+ and B+→KS0K+π-K+ decays based on the analysis of proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb-1. The KS0Kπ invariant-mass distributions of both B+ decay modes show, in the m(KS0Kπ)
