CERN LHC signals from warped extra dimensions

We study production of Kaluza-Klein gluons (KKG) at the Large Hadron Collider(LHC) in the framework of a warped extra dimension with the Standard Model (SM) propagating in the bulk. We show that the detection of KK gluon is since its production is suppressed by small couplings to the's constituents. Moreover, the KK gluon decays mostly to top pairs due to enhanced coupling and hence is broad. Nevertheless, we demonstrate that forKKG \ 4 TeV, 100 fb⁻¹ of data at the LHC can provide discovery of KK gluon. We utilize a sizeable left-right polarization asymmetry from the gluon resonance to maximize the signal significance, and we explore the feature of extremely highly energetic "top-jets". We briefly discuss how detection of electroweak gauge KK states (Z/W) faces a similar challenge their leptonic decays (``golden'' modes) are suppressed. Our analysis that other frameworks, for example little Higgs, which rely on UV via strong dynamics might face similar challenges, namely (1) production rates for the new particles (such as Z'), due to their``light-fermion-phobic'' nature, and (2) Difficulties in detection since the particles are broad and decay predominantly to third generation quarks and gauge bosons.
