摘要

利用 BESIII 探测器在 BEPCII 对撞机上收集的质心能量范围 2.000 至 2.644 GeV、总积分亮度 300 pb^{-1} 的 e+e−e^{+}e^{-} 碰撞数据样本，对过程 e+e−→K+K−π0π0e^{+}e^{-} \to K^{+}K^{-}\pi^{0}\pi^{0} 进行了分波分析。测量了过程 e+e−→K+K−π0π0e^{+}e^{-} \to K^{+}K^{-}\pi^{0}\pi^{0} 的总 Born 截面，以及子过程 e+e−→ϕπ0π0e^{+}e^{-} \to \phi \pi^{0}\pi^{0}、K+(1460)K−K^{+}(1460)K^{-}、K1+(1400)K−K^{+}_{1}(1400)K^{-}、K1+(1270)K−K^{+}_{1}(1270)K^{-} 和 K∗+(892)K∗−(892)K^{*+}(892)K^{*-}(892) 的 Born 截面随质心能量的变化。对于 e+e−→K+K−π0π0e^{+}e^{-} \to K^{+}K^{-}\pi^{0}\pi^{0} 和 ϕπ0π0\phi \pi^{0}\pi^{0} 的相应结果与 BaBar 一致且精度大幅提高。通过分析四个子过程 K+(1460)K−K^{+}(1460)K^{-}、K1+(1400)K−K^{+}_{1}(1400)K^{-}、K1+(1270)K−K^{+}_{1}(1270)K^{-} 和 K∗+K∗−K^{*+}K^{*-} 的截面，观测到一个质量为 MM = (2126.5 ±\pm 16.8 ±\pm 12.4)~MeV/c^{2}、宽度为 Γ\Gamma = (106.9 ±\pm 32.1 ±\pm 28.1)~MeV 的结构，总体统计显著性为 6.3 σ\sigma，尽管在子过程 e+e−→K1+(1270)K−e^{+}e^{-} \to K^{+}_{1}(1270)K^{-} 和 K∗+(892)K∗−(892)K^{*+}(892)K^{*-}(892) 中显著性非常有限。所观测结构的共振参数表明其可辨认为 ϕ(2170)\phi(2170)，因此结果为 ϕ(2170)\phi(2170) 的内在性质提供了有价值的输入。
