Exact Evaluation and Resummation of the Divergent Expansion for the Heisenberg-Euler Lagrangian

Exact Evaluation and Resummation of the Divergent Expansion for the Heisenberg-Euler Lagrangian

We devise a novel resummation prescription based on the method of finite-part integration [Galapon EA. 2017 Proc. R. Soc A 473, 20160567. (doi:10.1098/rspa.2016.0567)] to perform a constrained extrapolation of the divergent weak-field perturbative expansion for the Heisenberg-Euler Lagrangian to the...
