Quarkonium spectroscopy from lattice QCD — •Georg M. von Hippel — Institut für Kernphysik, Johannes-Gutenberg-Universität Mainz, 55099 Mainz, Germany

Lattice simulations remain the only known method to obtain a priori information about the spectrum of Quantum Chromodynamics (QCD). Recent progress both in theoretical formulations and algorithms now allows for the extraction of reliable information on the excited-state spectra of quarkonium. I will discuss some of the theoretical issues involved and review recent lattice results on both charmonium and bottomonium spectra, in particular also taking into account recent progress regarding the bottomonium hyperfine structure within non-relativistic QCD.
