摘要：

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.
