Abstract.

In several preceding studies, the explicitly covariant formulation of light-front dynamics was developed and applied to many observables. In the present study we show how in this approach the renormalization procedure for the first radiative corrections can be carried out. It requires separating out the contributions which depend on the orientation of the light-front plane. We calculate the electron self-energy as well as the renormalized QED \(\gamma e^-\to e^-\) and \(\gamma \to e^+e^- \) vertices. Our renormalization procedure is confirmed by recovering, in a straightforward way, the well-known analytical results obtained in the Feynman approach.
