论文摘要
我们研究了四夸克人的非依赖主义模型，该模型被认为是紧凑的，由diquark-antidiquark对组成。我们首次合适，基本上所有目前已知的45个介子的质量，包括迷人和底部的介子，以及预测tetraquarks和diquarks的质量。特别是，我们发现了四个轴向矢量diquarks的群众，即$ qc $，$ cc $，$ qb $和$ bb $，其中$ q = u，d $和24个地面tetraquarks，包括重型轻tetraquarks，包括重型tetraquarks（$ qc \ qc \ qc \ qu cc \ qc} $ qb ryak and ququark and ylline} （$ cc \ overline {cc} $和$ bb \ overline {bb} $）。通常，我们对$ qb \ overline {qb} $，$ cc \ overline {cc} $和$ bb \ Overline {bb} $的质量的结果很大程度上与其他报告的结果相当，而我们的质量比$ qc \ yline {qc} $更大的质量比以前更大。最后，我们确定了一些具有大量实验tetraquark候选者的四夸克人的预测，尤其是，我们发现$ψ（4660）$，$ z_b（10610）$和$ z_b（10650）$可以由模型描述。
We investigate a nonrelativistic model of tetraquarks, which are assumed to be compact and to consist of diquark-antidiquark pairs. We fit, for the first time, basically all currently known values for the measured masses of 45 mesons, including both charmed and bottom mesons, to the model and predict masses of tetraquarks as well as diquarks. In particular, we find masses of four axial-vector diquarks, i.e., $qc$, $cc$, $qb$, and $bb$, where $q = u,d$, and 24 ground-state tetraquarks, including both heavy-light tetraquarks ($qc\overline{qc}$ and $qb\overline{qb}$) and heavy tetraquarks ($cc\overline{cc}$ and $bb\overline{bb}$). In general, our results for the masses of $qb\overline{qb}$, $cc\overline{cc}$, and $bb\overline{bb}$ are largely comparable with other reported results, whereas our results for the masses of $qc\overline{qc}$ are slightly larger than what has been found earlier. Finally, we identify some of the obtained predictions for masses of tetraquarks with masses of experimental tetraquark candidates, and especially, we find that $ψ(4660)$, $Z_b(10610)$, and $Z_b(10650)$ could be described by the model.
