Schwinger pair production: Explicit Localization of the world-line instanton

High Energy Physics - Theory 2017-10-11 v3

Abstract

We present a simple proof that the imaginary part of the world-line path integral which computes the rate of Schwinger pair production of charged particles in a constant electric field, is given exactly by the semiclassical WKB limit.
