Abstract

The possibility of radiative effects that are due to interaction of fermions with the constant axial-vector background in the standard model extension is investigated. Electron-positron photo-production and photon emission by electrons and positrons were studied. The rates of these processes were calculated in the Furry picture. It was demonstrated that the rates obtained strongly depend on the polarization states of the particles involved. In consequence of this fact ultrarelativistic particles should occupy states with a preferred spin orientation, i.e., photons have the sign of polarization opposite to the sign of the effective potential, while charged particle are preferably in the state with the helicity coinciding with the sign of the effective potential. This leads to evident spatial asymmetries.
