- Аннотация: The possibility of radiative effects induced by fermion interaction with a constant axial-vector background field is studied within an extended standard model. The production of electron-positron pairs by photons and photon emission by electrons and positrons are examined. The rates of these processes are calculated within the Furry picture. It is shown that the rates obtained in this way depend strongly on the polarization states of the particles involved. As a result, Ultrarelativistic particles predominantly occupy specific spin states-namely, charged particles occur in states where the sign of the helicity is coincident with the sign of the effective potential, while photons have polarization of sign opposite to the sign of the effective potential. This leads to spatial asymmetries, which may give rise to observable phenomena in astrophysical and cosmological investigations.
