In string realizations of the Randall-Sundrum scenario, the higher-spin Reggeexcitations of Standard Model states localized near the IR brane are warpeddown to close to the TeV scale. We argue that, as a consequence of thelocalization properties of Randall-Sundrum models of flavour, the lightest suchresonance is the spin-3/2 excitation of the right-handed top quark over asignificant region of parameter space. A mild accidental cancellation allowsthis resonance to be as light or lighter than the Kaluza-Klein excitations ofthe Standard Model states. We consider from a bottom-up effective theory pointof view the production and possible observability of such a spin-3/2 excitationat the LHC and Tevatron. Current limits are weaker than might be expectedbecause of the excess of WWjj events at the Tevatron reported by CDF for aninvariant mass of 400-500 GeV.

On the possibility of light string resonances at the LHC and Tevatron from Randall-Sundrum throats
