AXION-ELECTROMAGNETIC WAVES

Diffraction of Electromagnetic Waves

The general method to obtain solutions of the Maxwellian equations from scalar representatives is developed and applied to the diffraction of electromagnetic waves. Kirchhoff’s integral is modified to provide explicit expressions for these representatives. The respective integrals are then evaluated using the method of stationary phase in two dimensions. Hitherto unknown formulae for the polari...

Electromagnetic Catalysis of the Radiative Decay of the Axion

The radiative decay of the axion a → γγ is investigated in an external electromagnetic field in DFSZ model in which axion couples to both quarks and leptons at tree level. The decay probability is strongly catalyzed by the external field, namely, the field removes the main suppression caused by the smallness of the axion mass. will be published in Phys. Lett. B Various extensions of the Standar...

Axion Decay of a Photon in an External Electromagnetic Field

An interaction of a pseudoscalar particle with two photons induced by an external electromagnetic field is used to study the photon decay γ → γa where a is a pseudoscalar particle associated with the Peccei-Quinn U(1) symmetry. The fieldinduced axion emission by photon is analyzed as a possible source of energy losses by astrophysical objects.
