Abstract

An analytical result for Euler-Heisenberg effective action, valid for electron spin g-factor |g|<2, was extended to the domain |g|>2 via discovered periodicity of the effective action. This allows for a simplified computation of vacuum instability modified by the electron's measured g=2.002319. We find a strong suppression of vacuum decay into electron positron pairs when magnetic fields are dominant. The result is reminiscent of mass catalysis by magnetic fields.
