We examine the reach at hadron colliders for the lightest warped Kaluza-Klein(KK) graviton G_1 in the Z(->l+l-) Z(->nu nu) channel, l=e,mu, withinRandall-Sundrum models of hierarchy and flavor where the Standard Model gaugefields and fermions propagate in the 5D bulk. The reconstructed Z and theaccompanying large missing energy allow for an efficient suppression ofbackgrounds. For reasonable parameters, a ~2(2.6) TeV G_1 can be discovered at5 sigma with 300 /fb (3 /ab) of 14 TeV LHC data via our "Z + missing energy"signal. Using this signal, the discovery reach for G_1 at a future 100 TeV ppcollider is estimated to be as high as ~10 TeV. We discuss mass determinationof the singly produced G_1, using the energy distribution of its visible (Z ->l+l-) decay product, by adapting a recently proposed method. Based on ouranalysis, a mass measurement at the ~5% level with ~3 /ab of the 14 TeV LHCdata can be feasible.
