Finite volume corrections to forward Compton scattering off the nucleon
J. Lozano, A. Agadjanov, J. Gegelia +2
We calculate the spin-averaged amplitude for doubly virtual forward Compton scattering off nucleons in the framework of manifestly Lorentz invariant baryon chiral perturbation theo…

Nucleon in a periodic magnetic field: Finite-volume aspects
Andria Agadjanov, Ulf-G. Meißner, Akaki Rusetsky
The paper presents an extension and a refinement of our previous work on the extraction of the doubly virtual forward Compton scattering amplitude on the lattice by using the backg…
