Meson spectroscopy, resonances and scattering on the lattice

Abstract

I discuss some recent progress in studying the spectra of mesons using first-principles lattice QCD calculations. In particular, I highlight some new results on resonances, near-threshold states and related scattering phenomena – this is an area which is very interesting experimentally and theoretically and where we have made significant advances in the last few years. I conclude with an outlook on future prospects.
