Extracting scattering amplitudes for arbitrary two-particle systems with one-particle left-hand cuts via lattice QCD
Abstract 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-hand branch cuts due to single-particle exchanges. The method first relates the finite-volume spectrum to an inf...
