Spin-states in multiphoton pair production for circularly polarized light
arXiv:1812.03130 · doi:10.1103/PhysRevD.99.096017
Abstract
Scalar and fermionic particle pair production in rotating electric fields is investigated in the nonperturbative multiphoton regime. Angular momentum distribution functions in above-threshold pair production processes are calculated numerically within quantum kinetic theory and discussed on the basis of a photon absorption model. The particle spectra can be understood if the spin states of the particle-antiparticle pair are taken into account.
