Using Non-Relativistic QCD (NRQCD), we study heavy quark mass dependence ofS-wave and P-wave bottomonium correlators for 0.42Tc <= T <= 2.09Tc and studyspectral functions of S-wave bottomonium states moving in a thermal bath atthese temperatures using Maximum Entropy Method with NRQCD kernel. For thestudied momentum range, the energy of moving states shows quadraticmomentum-dependence and the width of moving states does not show significantchanges as the momentum of bottomonium is increased. Also, we find that incorrelator ratios, the temperature effect is larger than the effect caused by20% change in the bottom quark mass.

Two topics from lattice NRQCD at non-zero temperature: heavy quark mass dependence and S-wave bottomonium states moving in a thermal bath
