Radion Mixing Effects on the Properties of the Standard Model Higgs Boson

Abstract

We examine how mixing between the Standard Model(SM) Higgs boson, $h$, and the radion of the Randall-Sundrum model modifies the expected properties of the Higgs boson. In particular, we demonstrate that the total and partial decay widths of the Higgs, as well as the $h\to gg$ branching fraction, can be substantially altered from their SM expectations, while the remaining Higgs branching fractions are modified less than $\lsim 5%$ for most of the parameter region.
