We present a nonperturbative recipe for directly computing the S-matrix in strongly-coupled QFTs. The method makes use of spectral data obtained in a Hamiltonian framework and can be applied to a wide range of theories, including potentially QCD. We demonstrate the utility of this prescription in the specific example of the 2+ 1d O (N) model at large N, using energy eigenstates computed with Hamiltonian truncation to reproduce the full 2→ 2 scattering amplitude for arbitrary (complex) center-of-mass energy.
