Non Linear Breaking of the Electroweak Symmetry and Large Extra Dimensions

Abstract

We consider the coupling to gravity in 4+delta dimensions of a non linear electroweak symmetry breaking sector, with delta compactified dimensions, and derive an effective lagrangian by integrating over the KK excitations of the graviton and of the dilaton. The effective chiral lagrangian describes the interactions of the electroweak gauge bosons and the goldstone bosons from the electroweak breaking.
