S wave bottomonium states moving in a quark-gluon plasma from lattice NRQCD
arXiv:1210.2903 · doi:10.1007/JHEP03(2013)084
Abstract
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 (Upsilon and eta_b) channels and consider nonrelativistic velocities, v/c < 0.2. A comparison with predictions from effective field theory is made.
