Poster Heavy flavor and quarkonia production


Jon-Ivar Skullerud (National University of Ireland Maynooth)


We study the temperature dependence of bottomonium for temperatures in the range $0.4 T_c < T < 2.1 T_c$, using nonrelativistic dynamics for the bottom quark and full relativistic lattice QCD simulations for $N_f=2$ light flavors on a highly anisotropic lattice. We find that the $\Upsilon$ is insensitive to the temperature in this range, while the $\chi_b$ propagators show a crossover from the exponential decay characterizing the hadronic phase to a power-law behaviour consistent with nearly-free dynamics at $T\simeq2T_c$.
