Higgs Phenomenology in Warped Extra Dimensions — •Raoul Malm, Christoph Schmell, and Matthias Neubert — Mainz Institute for Theoretical Physics, Johannes Gutenberg University, Mainz, Germany

Precise measurements of the Higgs-like boson couplings provide a test of the electroweak symmetry breaking sector and allow to search for physics beyond the Standard Model (SM). One of the promising theories, capable of explaining the gauge hierarchy problem and the flavor puzzle of the SM, is the Randall-Sundrum (RS) Model that extends space-time by one small, compact and strongly curved extra-dimension.

This talk presents a description of the Higgs couplings to SM quarks and bosons in RS models with a Higgs sector localized on or near the infra-red (IR) brane. The analytic results for all relevant Higgs couplings including the loop-induced couplings to gluons and photons are summarized, where it is distinguished between the minimal and the custodial, as well as the brane-Higgs and narrow bulk-Higgs scenario.
