Lepton pair creation in intense laser fields
The creation of particle-antiparticle pairs by multiphoton absorption from intense laser fields in various configurations is discussed.Electron-positron pair creation by high-energy proton impact on a strong laser beam is considered first, including spin and recoil effects. Acomparison is drawn with pair creation in relativistic electron-laser collisions. The creation of muon-antimuon pairs is also addressed.Finally, we consider electron-positron pair creation in a standing electromagnetic wave formed by two counter-propagating laser beams.
