We perform a model-independent partial wave analysis in the low K+K- mass region to determine the K+K- S-wave line shape, followed by an amplitude analysis of our very pure high-statistics sample. With the detection efficiency based on the amplitude analysis results, the absolute branching fraction is measured to be B(D-s(+) -> K+K-pi(+)) = (5.47 +/- 0.08(stat) +/- 0.13(sys))%.eninfo:eu-repo/semantics/openAccessScatteringDecayArticle2-s2.0-8511181552410.1103/PhysRevD.104.0120161Q1104Q1WOS:000680434500004
