- Аннотация: Creation of charged massless fermion pair by a photon in a constant uniform magnetic field is considered in the one-loop approximation of the (2 + 1)-dimensional quantum electrodynamics (QED2+1). We calculate the elastic scattering amplitude (EAS) of a photon using the polarization operator of photon in the above magnetic field obtained earlier in our work. We analyze the elastic scattering amplitude of photon at various values of the photon energy and magnetic field strength. Very simple analytical formulas for EAS of photon are obtained in the so-called quasi-classical region. In the massive quantum electrodynamics the elastic scattering amplitude of photon defines its "mass" squared in the presence of external electromagnetic field and the imaginarypart of EAS describes the total probability of charged massive fermion pair creation inthe electromagnetic field; we assume that it is the case and in the massless quantum electrodynamics.
