Description
Most of the known hadrons in the low-energy QCD spectrum are resonances observed in multiparticle scattering processes. First-principles determination of the properties of these unstable hadrons is a major goal of lattice QCD calculations. Significant progress has been made in the development, implementation and application of theoretical tools that relate finite-volume lattice QCD quantities to scattering amplitudes, allowing the masses and widths of different hadronic resonances to be determined. In this talk I will discuss recent advances in lattice QCD studies of meson-meson, meson-baryon and three-hadron resonances. Examples are $\sigma$, $\Lambda(1405)$ and $T_{cc}^+$.
