Multi-photon regime of non-linear Breit-Wheeler and Compton processes in short linearly and circularly polarized laser pulses

A. I. Titov, A. Otto, B. Kampfer

Non-linear Breit-Wheeler $e^{+}{e}^{-}$ pair production and its crossing channel - the non-linear Compton process - in the multi-photon regime are analyzed for linearly and circularly po…
