| Publication Abstract: | Focusing on three-pion states with maximal isospin (?+?+?+), we present the first non-perturbative determination of an energy-dependent three-hadron scattering amplitude from first-principles QCD. The calculation combines finite-volume three-hadron energies, extracted using numerical lattice QCD, with a relativistic finite-volume formalism, required to interpret the results. To fully implement the latter, we also solve integral equations that relate an intermediate three-body K matrix to the physical three-hadron scattering amplitude. The resulting amplitude shows rich analytic structures and a complicated dependence on the two-pion invariant masses, represented here via Dalitz-like plots of the scattering rate. |
