我们将夸克-胶子等离子体中底鎓谱函数的研究扩展到非零动量。我们采用格点QCD模拟，在高各向异性格点上，轻夸克有两种不同的味道，底夸克用非相对论QCD（NRQCD）处理。我们专注于S波（伽马和eta（B））通道，并考虑非相对论速度，v/c小于或接近0.2。与有效场论的预测进行了比较。
We extend our study of bottomonium spectral functions in the quark-gluon plasma to nonzero momentum. We use lattice QCD simulations with two flavours of light quark on highly anisotropic lattices and treat the bottom quark with nonrelativistic QCD (NRQCD). We focus on S wave (gamma and eta(b)) channels and consider nonrelativistic velocities, v/c less than or similar to 0.2. A comparison with predictions from effective field theory is made.
