| Title | Review: Multi-particle systems on the lattice and chiral extrapolations | ||||
| Abstract | At present, the extraction of two- and three-body hadronic scattering amplitudes and the properties of the low-lying hadronic resonances from the finite-volume energy levels in lattice QCD represents a rapidly developing field of research. The use of various modifications of the Luescher finite-volume method has opened a path to calculate infinite-volume scattering amplitudes on the lattice. Many new results have been obtained recently for different two- and three-body scattering processes, including the extraction of resonance poles and their properties from lattice data. Such studies, however, require robust parametrizations of the infinite-volume scattering amplitudes which rely on basic properties of S-matrix theory and - preferably - encompass the case of quark masses away from the physical point. Parametrizations of this kind, provided by unitarized Chiral Perturbation Theory, are discussed in the present review. Special attention is paid to three-body systems on the lattice, owi | ||||
