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…
Discretization effects in finite-volume scattering
Maxwell T. Hansen, Toby Peterken
We incorporate non-zero lattice-spacing effects into Lüscher's finite-volume scattering formalism. The new quantization condition takes lattice energies as input and returns a vers…
Finite-volume scattering on the left-hand cut
André Baião Raposo, Maxwell T. Hansen
The two-particle finite-volume scattering formalism derived by Lüscher and generalized in many subsequent works does not hold for energies far enough below the two-particle thresho…
Analytic expansions of multi-hadron finite-volume energies: I. Two-particle states
Dorota M. Grabowska, Maxwell T. Hansen
We derive analytic expansions for the finite-volume energies of weakly-interacting two-particle systems, using the general relations between scattering amplitudes and energies deri…
