Abstract
In this paper we study the ultraviolet and infrared behavior of the self-energy of a pointlike charge in the vector and scalar Lee-Wick electrodynamics in a dimensional space time. It is shown that in the vector case, the self-energy is strictly ultraviolet finite up to spatial dimensions, finite in the renormalized sense for any odd, infrared divergent for , and ultraviolet divergent for even. On the other hand, in the scalar case, the self-energy is striclty finite for , and finite, in the renormalized sense, for any odd.
