we study seaching for kaluza klein graviton production in large extra dimension models via 2 jet plus missing transverse momentum signatures at the lhc. we present results for both the signal and the dominant zjj and wjj background in a perturbatively reliable way, ensured by a ptmiss dependent cut on the jet transverse momentum. the 2 jet results are compared with the 1 jet case. although the 2 jet results have slightly lower sensitivity to the scale of extra dimensions, the distributions of the two jets and their correlation with the missing transverse momentum provide additional evidence for the production of an invisible massive object.
