We explore properties of the doubly charged vector tetraquark $Z_{\mathrm{V}}^{++}=[cu][\bar{s}\bar{d}]$ built of four quarks of different flavors using the QCD sum rule methods. The mass and current coupling of $Z_{\mathrm{V}}^{++}$ are computed in the framework of the QCD two-point sum rule approach by taking into account quark, gluon and mixed vacuum condensates up to dimension 10. The full width of this tetraquark is saturated by S-wave $Z_{\mathrm{V}}^{++}\to {\pi }^{+}{D}_{s1}{(2460)}^{+}$, ${\rho }^{+}{D}_{s0}^{⁎}{(2317)}^{+}$, and P-wave $Z_{\mathrm{V}}^{++}\to {\pi }^{+}{D}_s^{+},K^{+}{D}^{+}$ decays. Strong couplings required to find partial widths of aforementioned decays are calculated in the context of the QCD light-cone sum rule method and a soft-meson approximation. Our predictions for the mass $m=(3515\pm 125)\text{ MeV}$ and full width ${\mathrm{\Gamma }}_{\mathrm{full}}={156}_{-30}^{+56}\text{ MeV}$ of $Z_{\mathrm{V}}^{++}$ are useful to search for this exotic meson in various processes. Recently, the LHCb collaboration discovered neutral states $X_{0(1)}(2900)$ as resonance-like peaks in $D^{-}{K}^{+}$ invariant mass distribution in the decay $B^{+}\to D^{+}{D}^{-}{K}^{+}$. We argue that mass distribution of $D^{+}{K}^{+}$ mesons in the same B decay can be used to observe the doubly charged scalar $Z_{\mathrm{S}}^{++}$ and vector $Z_{\mathrm{V}}^{++}$ tetraquarks.

我们探索双电荷矢量四夸克的性质 $Z_{\mathrm{伏}}^{++}=[C你][\overline{秒}\bar{d}]$使用 QCD 总和规则方法由四种不同风味的夸克构成。的质量和电流耦合$Z_{\mathrm{伏}}^{++}$在 QCD 两点求和规则方法的框架内计算，考虑到了 10 维的夸克、胶子和混合真空凝聚。这个四夸克的全宽被S波饱和$Z_{\mathrm{伏}}^{++}\to {\pi }^{+}{D}_{秒1}{(2460)}^{+}$, ${\rho }^{+}{D}_{秒0}^{⁎}{(2317)}^{+}$, 和P波$Z_{\mathrm{伏}}^{++}\to {\pi }^{+}{D}_{秒}^{+},{钾}^{+}{D}^{+}$腐烂。找到上述衰减的部分宽度所需的强耦合是在 QCD 光锥和规则方法和软介子近似的上下文中计算的。我们对质量的预测$米=(3515\pm 125)\text{ 电动汽车}$ 和全宽 ${\mathrm{\Gamma }}_{\mathrm{满的}}={156}_{-30}^{+56}\text{ 电动汽车}$ 的 $Z_{\mathrm{伏}}^{++}$有助于在各种过程中寻找这种奇异的介子。最近，LHCb 合作发现了中性态$X_{0(1)}(2900)$ 作为共振峰 $D^{-}{钾}^{+}$ 衰变中的不变质量分布 ${乙}^{+}\to D^{+}{D}^{-}{钾}^{+}$. 我们认为，质量分布$D^{+}{钾}^{+}$相同B衰变中的介子可用于观察双电荷标量$Z_{\mathrm{秒}}^{++}$ 和向量 $Z_{\mathrm{伏}}^{++}$ 四夸克。
