Photon emission by electrons and positrons created in a strong slowly rotating magnetic field

We study the electrodynamic process in which a photon is emitted together with an e --e + pair in the presence of a strong slowly rotating magnetic field. In particular, the spectrum of photons produced in this way is calculated starting from an effective Lagrangian that allows at tree level for the process itself. The magnetic field strengths we have in mind are \(\sim 10^{14} \mathrm{G}\) in such a way that, although our model is an oversimplified version of the real physical situation, the results can be applied only in some particular astrophysical scenarios (magnetars, massive black holes).
