  "abstract": "We investigate the feasibility of precision counting experiments based on laser-electron beam interactions to verify strong-field quantum electrodynamic effects, with particular emphasis on the stochastic nature of photon emission, photon polarization, and spin asymmetry. A precise Monte-Carlo model is developed using photon packets with multi-dimensional phase-space weighting, hierarchical-mesh cumulative distribution functions, and a variable time-step method. This model quantitatively reproduces the highest edge of the photon energy spectrum and the positron yield in the previous SLAC E-144 experiment. The quantized radiation back-reaction determines the highest edge tail and thus the positron yield for higher laser intensities. The spin asymmetry in photon emission and spin flip determines photon polarization in the high-energy tail, while that in pair production can be observed through the large-angle positron scattering. Our simulations predict that these effects depend on the combination of the electron-beam energy and the laser intensity, and that they could be verified in future ELI-NP experiments using sub-GeV electron beams and optical lasers with intensities ~10^22W/cm2.",
