摘要：

We consider Standard Model fields living inside a thick four-dimensional flat brane embedded in a (possibly warped) five-dimensional space-time and estimate the electromagnetic corrections to the anomalous magnetic moment (g - 2) of the electron and muon by including virtual massive fermion and gauge boson states. Constraints on the mass of the "excited" states (or thickness of the brane-world) are obtained. (C) 2000 Elsevier Science B.V. All rights reserved.
