The discovery reach for the ADD-type Large Extra Dimension (LED) scenario in the CMS Experiment at the LHC is presented by looking at the Monojet + Missing Energy signature,
which arises as a result of a single graviton emission accompanied by a quark or gluon. Using Monte Carlo generated events, two LHC run scenarios were considered and
compared namely a center-of-mass energy of 14 TeV and integrated luminosity of 100 pb& / #8722 / 1, and a center-of-mass energy of 10 TeV and integrated luminosity of 200 pb& / #8722 / 1. Details from extensive trigger studies are presented and offline selection techniques that optimize the signal excess over backgrounds are highlighted. As a result of this study, it is shown that the existing Tevatron limits on the ADD model can be improved through the implementation of this analysis in CMS Experiment with a factor of 3 using the the early LHC data.
