Unitary perturbation theory on the light cone using adiabatic switching
Stéphane Munier
Light-cone perturbation theory is a powerful tool for calculating high-energy scattering amplitudes, particularly for quantum particles such as electrons, photons, or protons scatt…

Scattering from an external field in quantum chromodynamics at high energies: from foundations to interdisciplinary connections
Athanasia-Konstantina Angelopoulou, Anh Dung Le, Stéphane Munier
We review the factorization of the -matrix elements in the context of particle scattering off an external field, which can serve as a model for the field of a large nucleus. The…
