Studying three-particle systems with non-zero angular momentum via lattice QCD: Part 1

Recent progress in lattice QCD has allowed for the first determination of scattering processes involving three-hadron system. To date, all studies have been restricted to processes with zero total angular momentum. In this talk, we review the recent theoretical developments that will allow the study of systems with non-zero angular momentum from lattice QCD. In particular, we present the integral equations that the scattering amplitude of such system must satisfy. We also explain how these amplitudes can be constrained from finite-volume spectra, which can be obtained from lattice QCD calculations.
