Effective action for Dirac spinors in the presence of general uniform electromagnetic fields

Abstract

Some new expressions are found, concerning the one-loop effective action of four dimensional massive and massless Dirac fermions in the presence of general uniform electric and magnetic fields, with $\vec{E}\cdot \vec{H}\ne 0$ and ${\vec{E}}^2\ne {\vec{H}}^2$. The rate of pair-production is computed and briefly discussed.
