Complex effective actions and gravitational pair creation

High Energy Physics - Theory 2025-12-22 v1

Abstract

We use different methods to calculate the imaginary part of the gravitational effective action due to a massless scalar field, with a view on perturbative vs. non-pertubative and the results of ArXiv:2305.18521.
