and study spectral functions of S-wave bottomoniumstates movingin a thermalbathat these temperaturesusingMaximumEntropyMethod with NRQCD kernel. For the studied momentum range, the energy of moving statesshows quadraticmomentum-dependenceand the width of movingstates does not show significantchanges as the momentum of bottomonium is increased. Also, we find that in correlator ratios,the temperature effect is larger than the effect caused by 20% change in the bottom quark mass.The 30th International Symposium on Lattice Field Theory - Lattice 2012,June 24-29, 2012Cairns, Australia
