Abstract
We present results on the bottomonium spectrum at temperatures above and
below the deconfinement crossover temperature, Tc, from dynamical lattice QCD simulations.
The heavy quark is treated with a non-relativistic effective field theory on the
lattice and serves as a probe of the hot medium. Ensembles with a finer spatial lattice
spacing and a greater range of temperatures below Tc than those previously employed by
this collaboration are used. In addition, there are Nf = 2 + 1 flavours of Wilson clover
quark in the sea with M� � 400MeV and we perform a more careful tuning of the bottom
quark mass in this work. We calculate the spectral functions of S and P wave bottomonium
states using the maximum entropy method and confirm earlier findings on the survival of
the ground state S wave states up to at least 2Tc and the immediate dissociation of the
P wave states above Tc.
