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 $S$-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…
