  The hierarchy problem can by addressed by extending the four-dimensional
space-time to include an extra compact spatial dimension with non-trivial
"warped" metric, as first suggested by Randall and Sundrum. If the
Randall-Sundrum framework is realized in string theory, and if the Standard
Model particles propagate in the extra dimension, Regge excitations of the
Standard Model states should appear around the TeV scale. In a previous
publication, we proposed a field-theoretic framework to model the tensor
(spin-2) Regge partner of the gluon. Here, we use this framework to study the
collider phenomenology of this particle. We find that Regge gluon decays
involving Kaluza-Klein (KK) partners of Standard Model fields are very
important. In particular, the decay to two KK gluons (with one possibly
off-shell) dominates in most of the parameter space. This decay produces a very
distinctive experimental signature: four highly boosted top quarks. We present
a preliminary study of the detection prospects for this signal at the Large
Hadron Collider (LHC). We find that Regge gluons masses up to about 2 TeV can
be probed with 10 inverse femtobarns of data at 7 TeV center-of-mass energy.
With design luminosity at 14 TeV, the LHC should be sensitive to Regge gluon
masses up to at least 3.5 TeV.
