Randall-Sundrum models based on SU(2)_L * SU(2)_R with custodial symmetry are
compelling frameworks for building alternative models of electroweak symmetry
breaking. A particular feature of these models is the likely presence of light
Kaluza-Klein fermions related to the right-handed top quark. These can be as
light as a few hundred GeV and still compatible with EW precision constraints.
In this article, we study the detectability of four-W final states at the LHC,
which arise from the pair-production and tW decay of light Kaluza-Klein bottom
quarks as well as light Kaluza-Klein quarks carrying electric charge 5/3.Comment: 17 pages, 26 figure
