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…

Higher partial wave contamination in finite-volume 1-to-2 transitions
Toby Peterken, Maxwell T. Hansen
In their seminal work, Lellouch and Lüscher derived a conversion factor relating a finite-volume matrix element, calculable using numerical lattice QCD, with the infinite-volume de…
