Abstract

Large Extra Dimensions Models have been proposed to remove the hierarchy problem and give an explanation why the gravity is so much weaker than the other three forces. In this work, we present an analysis of Monte Carlo data events for new physics signatures of spin-2 Graviton in context of ADD model with total dimensions $D=4+\delta,$ $\delta = 1,2,3,4,5,6 $ where $ \delta $ is the extra special dimension, this model involves missing momentum $P_{T}^{miss}$ in association with jet in the final state via the process $pp(\bar{p}) \rightarrow G+jet$, Also, we present an analysis in context of the RS model with 5-dimensions via the process $pp(\bar{p}) \rightarrow G+jet$, $G \rightarrow e^{+}e^{-}$ with final state $e^{+}e^{-}+jet$. We used Monte Carlo event generator Pythia8 to produce efficient signal selection rules at the Large Hadron Collider with $\sqrt{s}$=14TeV and at the Tevatron $\sqrt{s}$=1.96TeV .
