Description
The vast majority of hadrons are not stable with respect to the strong interactions, and are seen as resonant enhancements in the scattering amplitudes of the lightest stable hadrons. Recent developments have enabled the determination of hadron resonance properties from lattice QCD, a first-principles approach whereby finite volume spectra are computed numerically, that are then used to constrain the infinite volume scattering amplitudes. A summary of the approach and several examples will be presented for resonances seen in coupled-channel scattering amplitudes in scalar ($J^P=0^+$), axial-vector ($J^P=1^+$) and exotic ($J^{PC}=1^{-+}$) quantum numbers.
