Description
I will review recent advances in the direct study of three-hadron interactions from lattice QCD. Building on the pioneering work of Lüscher, many lattice QCD calculations to date have employed mathematical relations connecting finite-volume energies and matrix elements to physical scattering and decay amplitudes. While applications to two-hadron channels are well established, those to three- or more hadron states are still being developed. In addition to outlining the key formalism, I will highlight recent theoretical developments (e.g. for DDπ and Nππ amplitudes) and applications (e.g. rho-to-pi-pi-pi scattering with a rigorously resonant rho). I will also discuss future prospects and open challenges.
