Effect of polarization on the structure of electromagnetic field and spatiotemporal distribution of $e^{+}{e}^{-}$ pairs by colliding laser pulses

Chitradip Banerjee, Manoranjan P. Singh

Electron-positron pair production by means of vacuum polarization in the presence of strong electromagnetic (EM) field of two counterpropagating laser pulses is studied. A 3-dimens…
