论文摘要
我们应用QCD总规则的方法来研究$ s q \ bar s \ bar q $ tetraquark状态，带有外来量子数$ j^{pc} = 3^{ - +} $，并提取最低状态的质量为$ 2.33^{+0.19} _ {+0.19} _ { - 0.16} _ { - 0.16} $ gev。为了构建相关的四夸克电流，我们需要明确添加协方差衍生物操作员。我们对其相关插值电流的系统分析表明：a）此状态井陷入$ p $ -p $ ρϕ/ω$ $，但没有进入$ρf_2（1525）/ωf_2（1525）/ωf_2（1525）/ϕf_2（1270）$ CHANNELS $ chinder，and b）$ k _ 2（892）$ k^*（892）（892）进入$ p $ - 波$ k^*（892）\ bar k^*（892）$ channel。
We apply the method of QCD sum rules to study the $s q \bar s \bar q$ tetraquark states with the exotic quantum number $J^{PC} = 3^{-+}$, and extract mass of the lowest-lying state to be $2.33^{+0.19}_{-0.16}$ GeV. To construct the relevant tetraquark currents we need to explicitly add the covariant derivative operator. Our systematical analysis on their relevant interpolating currents indicates that: a) this state well decays into the $P$-wave $ρϕ/ωϕ$ channel but not into the $ρf_2(1525)/ωf_2(1525)/ϕf_2(1270)$ channels, and b) it well decays into the $K^*(892) \bar K_2^*(1430)$ channel but not into the $P$-wave $K^*(892) \bar K^*(892)$ channel.
