Excited meson spectroscopy from lattice QCD
Abstract
I report on recent advances in using lattice QCD to study excited meson spectroscopy. I summarise new calculations of excited charmonia where by using novel techniques we have extracted an extensive spectrum, including states with exotic quantum numbers and non-exotic hybrids, with high statistical precision. Another highlight is a recent calculation of the spectrum of excited light isoscalar mesons which includes determinations of their flavour content, for example, the η-η' mixing angle. I will discuss work on mapping out energy-dependent scattering phase shifts which has application to the study of resonances and decays, and conclude with some comments on future prospects.
