# QED as a many-body theory of worldlines: General formalism and infrared structure

@article{Feal2022QEDAA, title={QED as a many-body theory of worldlines: General formalism and infrared structure}, author={Xabier Feal and Andrey Tarasov and Raju Venugopalan}, journal={Physical Review D}, year={2022} }

We discuss a reformulation of QED in which matter and gauge fields are integrated out explicitly, resulting in a many-body Lorentz covariant theory of 0+1 dimensional worldlines describing super-pairs of spinning charges interacting through Lorentz forces. This provides a powerful, string inspired definition of amplitudes to all loop orders. In particular, one obtains a more general formulation of Wilson loops and lines, with exponentiated dynamical fields and spin precession contributions, and…
