Radion-higgs mixing state at the LHC with the KK contributions to the   production and decay
  In this paper we study the higgs-radion system of the Randall-Sundum model where matter and gauge fields live in the bulk. We take into account the Kalza-Klein(KK) loop correction for the higgs and the raidion coupling to the gauge bosons. Inspired by the LHC data in 2011 where a sign of the higgs boson has been seen at 125 GeV, we fix the one of the mass eigenstate of the higgs-radion mixed state at 125 GeV, and scan over all the other parameters which have not been excluded by the 2011's data. We find the region of parameters where the scalar particle at 125 GeV have branching ratio larger or smaller than that of the Standard Model(SM) higgs significantly. The predicted ratio Br(ZZ)/Br(gamma gamma) also may be different from that of the SM higgs boson.
