Description
Meson spectra can provide essential information on low-energy
QCD, in particular about the confinement and decay mechanisms.
However, the very decay processes, be they real or virtual,
may distort the spectra via sizeable and non-uniform mass shifts.
Therefore, modern approaches account for quark-antiquark creation
and annihilation, as well as S-matrix unitarity and analyticity
of mesonic final states. The present talk will thus focus on
unitarised quark models and recent lattice results for meson
resonances, in confrontation with experiment.
