论文摘要
基于晶格非相关QCD（NRQCD）研究，我们为$υ（1s）$，$υ（2s）$和$υ（3s）$ in Vacuum以及Quark-Gluon Plasma及其Quark-gluon Plasma提出了伯特 - 盐分振幅的结果。我们的研究基于2+1风味$ 48^3 \ times 12 $ lattices使用高度改进的交错夸克（HISQ）动作产生，而斜向质量为$ 161 $ MEV。在零温度下，伯特 - 盐分幅度幅度遵循基于非相关电位模型的期望。在非零温度下，伯特盐钙振幅的解释结果更加细微，但与我们先前对QUARK-GLUON等离子体激发Upsilons的晶格QCD研究一致。
Based on lattice non-relativistic QCD (NRQCD) studies we present results for Bethe-Salpeter amplitudes for $Υ(1S)$, $Υ(2S)$ and $Υ(3S)$ in vacuum as well as in quark-gluon plasma. Our study is based on 2+1 flavor $48^3 \times 12$ lattices generated using the Highly Improved Staggered Quark (HISQ) action and with a pion mass of $161$ MeV. At zero temperature the Bethe-Salpeter amplitudes follow the expectations based on non-relativistic potential models. At non-zero temperatures, the interpretation of Bethe-Salpeter amplitudes turns out to be more nuanced, but consistent with our previous lattice QCD study of excited Upsilons in quark-gluon plasma.
