摘要

我们使用一个具有重夸克-反夸克势的Schr\ odinger方程来计算底态和调和态的束缚态质量，其中包括先前在势非相对论性QCD中推导的$1/m$和$1/m^2$的修正，并用晶格QCD计算。这是未来项目的准备步骤，我们计划考虑类似的修正来研究介子-介子最低阈值以上的夸克共振和四夸克。

Computation of masses of quarkonium bound states using heavy quark potentials from lattice QCD

We compute masses of bottomonium and charmonium bound states using a Schr\"odinger equation with a heavy quark-antiquark potential including $1/m$ and $1/m^2$ corrections previously derived in potential Non-Relativistic QCD and computed with lattice QCD. This is a preparatory step for a future project, where we plan to take into account similar corrections to study quarkonium resonances and tetraquarks above the lowest meson-meson thresholds.
