Abstract
We construct for the first time an energymomentum tensor for the electromagnetic field of a pbrane in arbitrary dimensions entailing finite energymomentum integrals The construction relies on distribution theory and is based on a Lorentzinvariant regularization followed by the subtraction of divergent and finite counterterms supported on the brane The resulting energymomentum tensor turns out to be uniquely determined We perform the construction explicitly for a generic flat brane For a brane in arbitrary motion our approach provides a new paradigm for the derivation of the otherwise divergent selfforce of the brane The so derived selfforce is automatically finite and guarantees by construction energymomentum conservation
