Bottomonium at Non-zero Temperature from Lattice Non-relativistic QCD

The temperature dependence of bottomonium states at temperatures above and below \(T_c\) is presented, using non-relativistic dynamics for the bottom quark and full relativistic lattice QCD simulations for two light flavors on a highly anisotropic lattice. We find that the S-waves (\(\Upsilon\) and...

Description
Summary:The temperature dependence of bottomonium states at temperatures above and below \(T_c\) is presented, using non-relativistic dynamics for the bottom quark and full relativistic lattice QCD simulations for two light flavors on a highly anisotropic lattice. We find that the S-waves (\(\Upsilon\) and \(\eta_b\)) show little temperature dependence in this range while the P wave propagators show a crossover from the exponential decay characterizing the hadronic phase to a power-law behavior consistent with nearly-free dynamics at approximately twice the critical temperature.
