摘要：
We present a comprehensive description of the Higgs-boson couplings to Standard Model fermions and bosons in Randall-Sundrum (RS) models with a Higgs sector localized on or near the infra-red brane. The analytic results for all relevant Higgs couplings including the loop-induced couplings to gluons and photons are summarized for both the minimal and the custodial RS model. The RS predictions for all relevant Higgs decays are compared with current LHC data, which already exclude significant portions of the parameter space. We show that the latest measurements are sensitive to KK gluon masses up to 22.7TeV x (y*/3) at 95% confidence level for anarchic 5D Yukawa couplings bounded from above by vertical bar(Y-f)(ij)vertical bar <= y*. We also derive the sensitivity levels attainable in the high-luminosity run of the LHC and at a future linear collider.
