Non-linear Breit-Wheeler process with linearly polarized beams

Abstract

We study the non-linear Breit-Wheeler process ${\vec{\gamma }}^{\prime }+\vec{L}\to e^{+}+e^{-}$ in the interaction of linearly polarized probe photons (${\vec{\gamma }}^{\prime }$) with a linearly polarized laser beam ($\vec{L}$). In particular, we consider the asymmetry of the total cross section and the azimuthal electron distributions when the polarizations of the photon and laser beams in the initial state are mutually perpendicular or parallel. Considering intense laser beams and the strong field asymptotic we explore essentially the multi-photon dynamics. The asymmetry exhibits some non-monotonic behavior depending on initial kinematic conditions; it depends sensitively on the laser pulse duration. Our results provide additional knowledge for studying non-linear multi-photon effects in quantum electrodynamics and may be used in planning experiments in upcoming laser facilities.
