Abstract
I present a lattice-QCD calculation of the max-isospin,3-pion scattering amplitude (3pi+to3pi+).The calculation combines finite-volume energies with a relativistic field-theoretic formalism,required to interpret the results.I will describe the full work-flow required to reach the final amplitude,implemented here for the first time, and discuss the complicated singularities appearing in the latter.I will discuss how the approach promises to be a powerful tool for resonant three-particle systems
