Dressed Dirac Propagator from a Locally Supersymmetric $\mathcal{N}=1$ Spinning Particle

Olindo Corradini, Gianluca Degli Esposti

We study the Dirac propagator dressed by an arbitrary number $N$ of photons by means of a worldline approach, which makes use of a supersymmetric $\mathcal{N}=1$ spinning particle m…
