Finite volume corrections to forward Compton scattering off the nucleon

High Energy Physics - Lattice 2021-02-24 v1

Abstract

We calculate the spin-averaged amplitude for doubly virtual forward Compton scattering off nucleons in the framework of manifestly Lorentz invariant baryon chiral perturbation theory at complete one-loop order O(p4)O(p^4). The calculations are carried out both in the infinite and in a finite volume. The obtained results allow for a detailed estimation the finite-volume corrections to the amplitude which can be extracted on the lattice using the background field technique.
