Query: Warped Gravitons at the LHC and Beyond   We study the production and decay of Kaluza-Klein (KK) gravitons at the Large
Hadron Collider (LHC), in the framework of a warped extra dimension in which
the Standard Model (SM) fields propagate. Such a scenario can provide solutions
to both the Planck-weak hierarchy problem and the flavor puzzle of the SM. In
this scenario, the production via $q \bar{q}$ annihilation and decays to the
conventional photon and lepton channels are highly suppressed. However, we show
that graviton production via gluon fusion followed by decay to longitudinal
$Z/W$ can be significant; vector boson fusion is found to be a sub-dominant
production mode. In particular, the ``golden'' $ZZ$ decay mode offers a
distinctive 4-lepton signal that could lead to the observation at the LHC with
300 fb$^{-1}$ (SLHC with 3 ab$^{-1}$) of a KK graviton with a mass up to $\sim
2$ ($\sim 3$) TeV for the ratio of the AdS$_5$ curvature to the Planck scale
modestly above unity. We argue that (contrary to the lore) such a size of the
curvature scale can still be within the regime of validity of the framework.
Upgrades beyond the SLHC luminosity are required to discover gravitons heavier
than $\sim 4$ TeV, as favored by the electroweak and flavor precision tests in
the simplest such models.
