Effects of fermion localization in Higgsless theories and electroweak constraints
Physics Letters B
Extra-dimensional Higgsless models with electroweak symmetry breaking through boundary conditions generically have difficulties with electroweak precision constraints, when the fermions are localized to the "branes" in the fifth dimension. In this paper we show that these constraints can be relaxed by allowing the light fermions to have a finite extent into the bulk of the fifth dimension. The T and U electroweak parameters can be naturally suppressed by a custodial symmetry, while the Sdoi:10.1016/j.physletb.2004.11.055 fatcat:tweftuedura63bgworcc32epj4
