论文摘要
我们使用晶状体QCD静态静态光电位研究了$ i = 0 $底元结合状态和S，P，D和F波的共振。我们考虑五个耦合的频道，一个密封的Quarkonium和四个打开$ B^{（*）} \ bar {b}^{（*）} $和$ b^{（*）} _ s \ bar {b}^{b}^{（*）} 矩阵。我们讨论质量和衰减宽度的结果，并将其与现有的实验结果进行比较。此外，我们确定这些状态的夸克和梅森 - 梅森组成，以澄清它们是普通的Quarkonium还是应该将其解释为四夸克人。
We investigate $I = 0$ bottomonium bound states and resonances in S, P, D and F waves using lattice QCD static-static-light-light potentials. We consider five coupled channels, one confined quarkonium and four open $B^{(*)}\bar{B}^{(*)}$ and $B^{(*)}_s\bar{B}^{(*)}_s$ meson-meson channels and use the Born-Oppenheimer approximation and the emergent wave method to compute poles of the T matrix. We discuss results for masses and decay widths and compare them to existing experimental results. Moreover, we determine the quarkonium and meson-meson composition of these states to clarify, whether they are ordinary quarkonium or should rather be interpreted as tetraquarks.
