我们研究了KAON对的共鸣贡献，该贡献源自中级状态$ρ（770,1450,1700）$和$ω（782,1420,1650）$ $ρ（782,1420,1650）$，用于三体Hadronic衰减$ b \ b \ bar k \ bar k H $ to K \ bar k H $在扰动QCD接近$ h =（$ h =（$ h =（$ h）中， $ k \ bar k $的虚拟贡献的分支部分从$ρ（770）$和$ω（782）$的$ k \ bar k $中，在这些衰减的实验性和理论研究中被忽略了，比共振$ρ（1450,1700,1700）$ $ $ρ（1450,1450）（1420）（1420）（1420 $ρ（1450,1700）$ρ（1450,1420）发现。 $ b \至ρ（770）h \至k \ bar k h $和$ b \toΩ（782）h \至k \ bar k h $的微分分支分数几乎不受本文中$ρ（770）$ $ρ（770）$和$ω$的全部宽度的完全不同的影响。这项工作的预测对准体的分支分数衰减$ b^+\ toπ^+ρ（1450）^0 \toπ^+k^+k^ - $和$ b^+\toπ^+ρ（1450）^0 \ toπ^+π^+π^+π^+π^ - $ sements $ sements $ suement of（3）。
We study the resonance contributions for the kaon pair originating from the intermediate states $ρ(770,1450,1700)$ and $ω(782,1420,1650)$ for the three-body hadronic decays $B\to K\bar K h$ in the perturbative QCD approach, where $h=(π, K)$. The branching fractions of the virtual contributions for $K\bar K$ from the Breit-Wigner formula tails of $ρ(770)$ and $ω(782)$ which have been ignored in experimental and theoretical studies for these decays are found larger than the corresponding contributions from the resonances $ρ(1450,1700)$ and $ω(1420,1650)$. The differential branching fractions for $B\to ρ(770) h\to K\bar K h$ and $B\toω(782) h \to K\bar K h$ are found nearly unaffected by the quite different values of the full widths for $ρ(770)$ and $ω(782)$ in this paper. The predictions in this work for the branching fractions of the quasi-two-body decays $B^+\to π^+ ρ(1450)^0\to π^+K^+K^-$ and $B^+\to π^+ ρ(1450)^0\to π^+π^+π^-$ meet the requirement of $SU(3)$ symmetry relation.
