Warped Extra Dimension Phenomenology

Abstract: 

Among all the extra dimensional extensions of the Standard Model of particle physics (SM) at the TeV scale, 5D warped extra dimensions are the most attractive. Their first modern motivation was to address the Planck-weak hierarchy problem of the SM; the fact that there is a 15 orders of magnitude difference between the Planck scale (∼ 1018 GeV) and the weak scale (∼ 1 TeV). It was soon realized that the same mechanism that solves the Planck-weak hierarchy problem, can be used to explain yet another hierarchy of the SM; the hierarchy between the observed masses of the fermions, from the top quark ($m_t \approx 10^2$ GeV) down to the light neutrinos ($m_\nu \approx 5 \times 10^{−2}$ eV).

In this context, after introducing the model, I present the phenomenology of the Higgs boson at the Large Hadron Collider (LHC). I discuss that with simple modifications, the results are generically consistent with the current experimental results for new physics as low as 2 TeV, that is, within the reach of the LHC.
