Abstract: In the context of warped scenarios in which Standard Model SM fields areallowed to propagate in the bulk, we revisit the possible mixing between the IRlocalized Higgs field and the Radion graviscalar. The phenomenology of theresulting mostly-Higgs field does not suffer important deviations with respectto the case in which all the SM is localized in the IR brane originalHiggs-Radion mixing scenario. On the contrary, the phenomenology of themostly-Radion field can present important differences with respect to theoriginal scenario. At the LHC, the most striking effect is now the possibilityof sizeable Radion decays into photons in a mass range well beyond the ZZ andWW thresholds, not due to dramatically enhanced couplings to photons but tosuppressed couplings to massive fields.
