  Spin-2 particles and in particular gravitons are predicted in many new
physics scenarios at the TeV scale. Depending on the details of models such new
states might show up as a continuum, massless particles, or TeV scale
resonances. Correspondingly, very different discovery signatures should be
exploited, from the search of excesses in events with multi jets and large
missing transverse energy, to resonances in weak boson or jet pair productions.
We present a very general and flexible implementation in MadGraph/MadEvent of
spin-2 particles interacting with the standard model particles via the energy
momentum tensor, which encompasses all of the most popular TeV scale models
featuring gravitons. By merging matrix elements with parton shower, we can
generate inclusive samples of graviton+jets at the hadron colliders in several
scenarios (ADD, zero-mass graviton and RS). We compare and validate our results
against the corresponding next-to-leading order QCD calculations.
