Gero von Gersdorff
TL;DR
This paper reviews electroweak symmetry breaking within warped extra-dimensional models, focusing on a bulk Higgs and deformed metric to mitigate precision test constraints and improve model viability.
Contribution
It introduces a novel warped extra-dimensional model with a bulk Higgs and deformed metric that reduces Kaluza-Klein contributions to electroweak observables.
Findings
Model reduces Kaluza-Klein effects on precision tests
Deformed metric near IR boundary softens Higgs-KK coupling
Enhanced compatibility with electroweak constraints
Abstract
We review Electroweak breaking in warped Extra Dimensions and show how it is constrained by Electroweak precision tests. We then proceed to describe a model which is based on a bulk Higgs field and a metric that is deformed from the usual five dimensional Anti de Sitter space near the Infrared (IR) boundary. It allows to softly decouple the Higgs field from the Kaluza Klein excitations near the IR and thus reduces their contribution to the precision observables.
