利用底夸克的非相对论动力学和两种不同光味的全相对论格点QCD模拟，给出了底夸克态在温度高于和低于温度时的温度依赖性.我们发现，S-波（和）在这个范围内表现出很小的温度依赖性，而P波传播显示出交叉的指数衰减特征的强子阶段的幂律行为符合近自由动力学在大约两倍的临界温度。
The temperature dependence of bottomonium states at temperatures above and belowis presented, using non-relativistic dynamics for the bottom quark and full relativistic lattice QCD simulations for two light flavors on a highly anisotropic lattice. We find that the S-waves (and) show little temperature dependence in this range while the P wave propagators show a crossover from the exponential decay characterizing the hadronic phase to a power-law behavior consistent with nearly-free dynamics at approximately twice the critical temperature.
