| Abstract: | We adapt  string-inspired worldline techniques to one-loop calculations on orbifolds, in particular on the S1/Z2 orbifold. Our method also allows for the treatment of brane-localized terms, or bulk-brane couplings. For demonstration, we reproduce the well-known result for the one-loop induced Fayet-Iliopoulos term in rigidly supersymmetric Abelian gauge theory, and generalize it to the case where soft supersymmetry breaking mass terms for the bulk scalar fields are present on the branes.Received: 10 January 2005, Published online: 11 May 2005 |
