论文摘要
受到对矢量charmon的状态$ y（4626）的首次观察的启发状态，我们预测潜在的矢量炭状状态$ y $，带有$ p $ -Wave stalar-scalar $ [cq] [\ bar {c} \ bar {q}] $ configuration。 $ y $状态的相应质谱在QCD SUM规则的框架中计算为$ 4.33^{+0.16} _ { - 0.23}〜\ mbox {gev} $。我们建议可以在开放式$ e^{+} e^{ - } \ rightarrow \ bar {d} d_ {1}（2420）+c.c. $ process中寻找预测的$ y $状态。
Inspired by the first observation of a vector charmonium-like state $Y(4626)$ decaying to a meson pair $D_{s}^{+}D_{s1}(2536)^{-}$, which could be viewed as a $P$-wave scalar-scalar $[cs][\bar{c}\bar{s}]$ tetraquark state, we predict a potential vector charmonium-like state $Y$ with $P$-wave scalar-scalar $[cq][\bar{c}\bar{q}]$ configuration. The corresponding mass spectrum of $Y$ state is calculated to be $4.33^{+0.16}_{-0.23}~\mbox{GeV}$ in the framework of QCD sum rules. We suggest that the predicted $Y$ state could be looked for in an open-charm $e^{+}e^{-}\rightarrow\bar{D}D_{1}(2420)+c.c.$ process.
