Informal Pizza SeminarSpontaneous Localization of Bulk Matter FieldsStefan Groot NibbelinkUniversity of VictoriaSome supersymmetric orbifold models in 5 dimensions with a U(1) vector multiplet and hyper multiplets in the bulk are unstable. The Fayet-Iliopoulos terms generated at the one loop level, are proportional to delta-functions and their double derivatives at the two boundaries. A consequence of this is that the zero modes of the hyper multiplets get localized on one or both branes. Some consequences for orbifold model building and anomaly considerations are discussed.
