LHC Signatures of Warped-space Vectorlike Quarks    [PDF]

Shrihari Gopalakrishna, Tanumoy Mandal, Subhadip Mitra, Gregory Moreau
We study the LHC signatures of TeV scale vectorlike quarks $b'$, $t'$ and $\chi$ with electromagnetic charges -1/3, 2/3 and 5/3 that appear in many beyond the standard model (BSM) extensions. We consider warped extradimensional models and analyze the phenomenology of such vectorlike quarks that are the custodial partners of third generation quarks. In addition to the usually studied pair-production channels which depend on the strong coupling, we put equal emphasis on single production channels that depend on electroweak couplings and on electroweak symmetry breaking induced mixing effects between the heavy vectorlike quarks and standard model quarks. Although the motivation is from warped models, we present many of our results model-independently.
