Query: Radion-Higgs mixing effects on bounds from LHC Higgs Searches   The radion, a scalar particle associated with the radius of a compact warped
extra dimension, may be the lightest new particle in this class of models. Its
couplings to SM particles are proportional to the their masses, similar to the
usual Higgs boson, but suppressed by a scale $\Lambda_r$, the radion vacuum
expectation value. The main differences are the coupling to massless gauge
bosons that receives contribution from the trace anomaly of the energy-momentum
tensor due to the the nonvanishing $\beta$ functions and the mixing with the
Higgs boson arising from a nonminimal coupling to gravity parametrized by a
dimensionless coefficient $\xi$. In particular, these differences can result in
significant modifications of the radion phenomenology.We use current LHC data
on Higgs searches to find exclusion regions on the parameters of a radion
model, $\Lambda_r$, $\xi$ and the radion mass $m_r$. We find that, even for low
values of $\Lambda_r$, the radion can still have a mass in the region where the
Standard Model Higgs has been excluded, for a narrow range of values for the
mixing parameter. Some signals at the LHC for this scenario are discussed.We
also find that it is possible to hide the Higgs boson in the current searches
in this model, due to a suppression of its couplings.
