(color online) (a) Polar distributions of target electron, γ-photon, and positron intensities at times t = 10.0T₀ and 10.25T₀ and (b) polar distributions of target electron, γ-photon, BW-electron, and positron intensities at t = 14.5T₀, for p-polarized laser. Azimuthal distributions of target electron, γ-photon, and positron intensities at t = 10.0T₀ and 10.25T₀, for (c) p- and (d) s-polarized lasers. In panels (a), (c), and (d), the black, cyan, and blue solid lines represent target electrons, γ-photons, and positrons, respectively, at t = 10.0T₀; the magenta, green, and red dashed lines indicate target electrons, γ-photons, and positrons, respectively, at t = 10.25T₀; the polar distribution of BW-electron intensity displays a similar pattern as that of the positron, thus is not shown here.
