Graviton production with 2 jets at the LHC in large extra dimensions

We study Kaluza- Klein ( KK) graviton production in the large extra dimensions model via 2 jets plus missing transverse momentum signatures at the LHC. We make predictions for both the signal and the dominant Zjj and Wjj backgrounds, where we introduce missing P-T-dependent jet selection cuts that ensure the smallness of the 2- jet rate over the 1- jet rate. With the same jet selection cuts, 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.
