Yukawa Couplings for the Spinning Particle and the World Line Formalism
Myriam Mondragon, Lukas Nellen, Michael G. Schmidt, Christian Schubert
Abstract
We construct the world-line action for a Dirac particle coupled to a classical scalar or pseudo-scalar background field. This action can be used to compute loop diagrams and the effective action in the Yukawa model using the world-line path-integral formalism for spinning particles.
