TL;DR
This paper investigates how a quartic interaction between Higgs and Goldberger-Wise fields affects Higgs-radion mixing in stabilized brane world models, analyzing constraints from LHC data.
Contribution
It introduces a novel coupling mechanism linking extra dimension stabilization with Higgs symmetry breaking, impacting Higgs-radion mixing analysis.
Findings
Higgs-radion mixing can be significantly influenced by the quartic interaction.
LHC data impose restrictions on model parameters related to this coupling.
The study provides bounds on the radion mass and coupling strength.
Abstract
We consider a quartic interaction of the Higgs and Goldberger-Wise fields, which connects the mechanism of the extra dimension size stabilization with spontaneous symmetry breaking on our brane and gives rise to a coupling of the Higgs field to the radion and its KK tower. We estimate a possible influence of this coupling on the Higgs-radion mixing and study restrictions on model parameters from the LHC data.
