A partial-wave analysis of the decay J/ψ → K+ K−π0 made using (223.7 ± 1.4) 106 J/ψ events collected with the BESIII detector in 2009 [1] will be presented and discussed. We report the most precise measurements of K*(892)± and K2*(1430)± mass and width. The analysis reveals contributions from K2*(1980)± and K4*(2045)± for the first time in J/ψ decays. Two resonance signals decaying to K+K− are also observed and their possible interpretations will be discussed. Results also include branching fractions for decays through intermediate states and a high precision measurement of B(J/ψ → K+ K−π0). The results of the partial-wave analysis differ significantly from those reported earlier by the BESII and BABAR Collaborations.
