In the present work, we study the Okubo-Zweig-Iizuka-allowed three body open flavor decay properties of higher vector charmonium and bottomonium states with an extended quark pair creation model. For the bottomonium system, we get that (i)?the B B π and B * B * π partial decay widths of the ? ( 10860 ) state are consistent with the experiment, and the B B * π partial decay width of the ? ( 10860 ) state is smaller but very close to Belle’s experiment. Meanwhile, (ii)?the B B * π and B * B * π decay widths of ? ( 11020 ) can reach 2–3?MeV. In addition, (iii)?for most of the higher vector charmonium states, the partial decay widths of the D D * π and D * D * π modes can reach up to several MeV, which may be observed in future experiments.
