Extracting scattering amplitudes for arbitrary two-particle systems with one-particle left-hand cuts via lattice QCD

André Baião Raposo, Raúl A Briceño, Maxwell T Hansen +1

We derive a general formalism that relates the spectrum of two-particle systems in a finite volume to physical scattering amplitudes, taking into account the presence of any left-h…
