Propagator in the nonlocal Bloch–Nordsieck model

A. V. Kiselev, A. Ya. Rodionov


Abstract: The fermion two-point Green's function for the Bloch–Nordsieck model is considered in the case of a nonlocal interaction. An exact expression for it is obtained by means of functional integration and also by solving the Schwinger–Dyson equation. The infrared and ultraviolet asymptotic behaviors are investigated.
