  Abstract A study is presented of B+ -> (KSK-)-K-0 pi K-+(+) and B+ -> (KSK+)-K-0 pi 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 (KSK)-K-0 pi invariant-mass distributions of both Bthorn decay modes show, in the m((KSK)-K-0 pi) < 1.85 GeV mass region, large activity which is resolved using an amplitude analysis. A simple model, where J(PC) amplitudes are described by multiple Breit-Wigner functions with appropriate angular distributions, provides a good description of the experimental data. In this approach a complex mixture of J(PC) = 0(-+), 1(++) and 1(-+) amplitudes is observed that is dominated by eta(1405), eta(1470), eta(1760), f 1o1285THORN, f(1)(1420) and h(1)(1405) resonances. The (KSK)-K-0 pi Dalitz plots are dominated by asymmetric crossing K*(K) over bar bands which are different for the two Bthorn decay modes. This is due to a different interference pattern between the 1(++) and 1(+-) amplitudes in the two channels. Branching fractions are measured for each resonant contribution.
