Abstract:
The classic Abraham-Lorentz-Dirac self-force of point-like particles is
generalized within an effective field theory setup to include linear spin and
susceptibility effects described perturbatively, in that setup, by effective
couplings in the action. Electromagnetic self-interactions of the point-like
particle are integrated out using the in-in supersymmetric worldline quantum
field theory formalism. Divergences are regularized with dimensional
regularization and the resulting equations of motion are in terms only of an
external electromagnetic field and the particle degrees of freedom.
