Functional integral over velocities for a spinning particle with and without anomalous magnetic moment in a constant electromagnetic field
Wellington da Cruz
Abstract
The technique of functional integration over velocities is applied to the calculation of the propagator of a spinning particle with and without anomalous magnetic moment. A representation for the spin factor is obtained in this context for the particle in a constant electromagnetic field. As a by-product, we also obtain a Schwinger representation for the first case.
