Scalar propagator in a background gluon field beyond the eikonal approximation
Abstract We investigate the path integral representation of the scalar propagator in a background gluon field, extending beyond the eikonal approximation by considering all gauge field components and incorporating its x − dependence. Utilizing the worldline formalism, we integrate the Schwinger prop...
