Anomalies, Fayet-Iliopoulos terms, and the consistency of orbifold field theories
Riccardo Rattazzi, Claudio Scrucca, Roberto Contino
We study the consistency of orbifold field theories and clarify to what extent the condition of having an anomaly-free spectrum of zero modes is sufficient to guarantee it. Preservation of gauge invariance at the quantum level is possible, although at the ...
2002Running and matching from 5 to 4 dimensions
Riccardo Rattazzi, Roberto Contino
We study 5-dimensional grand-unified theories in an orbifold geometry by the method of effective field theory: we match the low and high energy theories by integrating out at 1-loop the massive Kaluza-Klein states. In the supersymmetric case the radius dep ...
2002Graviton loops and brane observables
Riccardo Rattazzi, Roberto Contino
We discuss how to consistently perform effective Lagrangian computations in quantum gravity with branes in compact extra dimensions. A reparametrization invariant and infrared finite result is obtained in a non trivial way. It is crucial to properly accoun ...
