Abstract
The propagators related to a Dirac particle with anomalous magnetic moment in the presence of a plane wave field are exactly and analytically calculated via the path integral approach in two representations: a global and a local one. It is shown that due to two identities, one bosonic and another fermionic, the path integral calculations are evaluated essentially on classical paths projected along the wave propagation k. Special cases are considered as well.
