Bottomonium above deconfinement in lattice nonrelativistic QCD

Abstract

We study the temperature dependence of bottomonium for temperatures in the range $0.4T_c<T<2.1T_c$, 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 ${\rm Y}$ 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 $T\simeq 2T_c$.
