Gauge symmetry breaking on orbifolds
Carla Biggio
Abstract
We discuss a new method for gauge symmetry breaking in theories with one extra dimension compactified on the orbifold S1/Z2. If we assume that fields and their derivatives can jump at the orbifold fixed points, we can implement a generalized Scherk-Schwarz mechanism that breaks the gauge symmetry. We show that our model with discontinuous fields is equivalent to another with continuous but non periodic fields; in our scheme localized lagrangian terms for bulk fields appear.
