Impossibility of obtaining a CP-violating Euler-Heisenberg effective theory from a viable modification of QED

M. Ghasemkhani, V. Rahmanpour, R. Bufalo +1

In this paper, we examine the CP-violating term of the Euler-Heisenberg action. We focus in the aspects related with the generation of such a term from a QED-like model in terms of…
