Resumo

In this letter we study the self-energy of a point-like charge for the electromagnetic field in a non-minimal Lorentz symmetry breaking scenario in a (n + 1)-dimensional space time. We consider two variations of a model where the Lorentz violation is caused by a background vector d(nu) that appears in a higher derivative interaction. We restrict our attention to the case where d(mu) is a time-like background vector, namely d(2) = d(mu)d(mu) > 0, and we verify that the classical self-energy is finite for any odd spatial dimension n and diverges for even n. We also make some comments regarding obstacles in the quantization of the proposed model. Copyright (C) EPLA, 2018. (AU)
