The angular dependence of the differential cross section of unpolarizedlight-by-light scattering summed over final polarizations is the same in anylow-energy effective theory of quantum electrodynamics and also in Born-Infeldelectrodynamics. In this paper we derive general expressions forpolarization-dependent low-energy scattering amplitudes, including ahypothetical parity-violating situation. These are evaluated for quantumelectrodynamics with charged scalar or spinor particles, which give strikinglydifferent polarization effects. Ordinary quantum electrodynamics is found toexhibit rather intricate polarization patterns for linear polarizations,whereas supersymmetric quantum electrodynamics and Born-Infeld electrodynamicsgive particularly simple forms.
