Going to the light front with contour deformations
Gernot Eichmann, Eduardo Ferreira, Alfred Stadler
Abstract
This work introduces a new method for computing correlation functions on the light front. Starting from Bethe-Salpeter equations, the authors present calculations using contour deformation and analytic continuation, finding good agreement with established methods. This approach shows promise as an efficient and generalizable technique with applications to parton distribution functions and related constructions.
