The high temperature QCD static potential: A higher order calculation

We calculate the real-time quantum chromodynamic (QCD) static potential in a high temperature medium, beyond the leading order Hard Thermal Loop (HTL) approximation, in the region where bound states change from narrow resonances to wide ones. The calculation uses the method of integration by regions. We also calculate corrections to the spectrum of bottomonium and estimate the dissociation temperature of the ground state. We compare our results with recent lattice data and discuss the usefulness of our results to guide lattice inputs.
