Abstract

Deep understanding of photon polarization impact on pair production is
essential for the efficient creation of laser driven polarized positron beams,
and demands a complete description of polarization effects in strong-field QED
processes. We investigate, employing fully polarization resolved Monte Carlo
simulations, the correlated photon and electron (positron) polarization effects
in multiphoton Breit-Wheeler pair production process during the interaction of
an ultrarelativistic electron beam with a counterpropagating elliptically
polarized laser pulse. We showed that the polarization of e^-e^+ pairs is
degraded by 35\%, when the polarization of the intermediate photon is resolved,
accompanied with an approximately 13\% decrease of the pair yield. Moreover,
the polarization direction of energetic positrons in small angle region is
reversed, which originates from the pair production of hard photons with
polarization parallel with electric field.
