Collider constraints on Gauss-Bonnet coupling in warped geometry model

In this paper the requirement of a warp solution in an Einstein-Gauss-Bonnet 5D warped geometry is shown to fix the signature of Gauss-Bonnet coupling ($α_{5}$). Further, imposing the phenomenological constraints, obtained from the recently observed Higgs like scalar mass as well as $μ$ parameter of the decay channels ${H}_{0}\rightarrowγγ,τ{\bar τ}$ explored in ATLAS and CMS detectors, we obtain a stringent bound on $α_{5}$ within $(4.8 - 5.1)\times 10^{-7}$.
