Description

Advances in Lattice QCD computations of the excited hadron spectrum require analytic representation of infinite volume three particle scattering amplitudes. We present a representation of the elastic three particle scattering amplitude consistent with the unitarity of the S-matrix. We investigate aspects of its analytic properties, specifically one-particle exchange effects and triangle singularities.
