Search for Mono-Jet Final States from ADD Extra-Dimensions at sqrt(s)=10 TeV

The missing transverse energy + single-jet signature has been investigated with the CMS detector, as a probe for the discovery of large extra dimensions in the framework of the ADD model. Signal and background samples have been simulated and analyzed. Techniques to estimate the background contributions via data-driven methods are discussed. The discovery reach is studied for the 2009/2010 running conditions of the LHC pp collider ($\sqrt{s}=10$\,\TeV, O(100)\,\pbinv ) taking into account systematic uncertainties. It is shown that a significant improvement to the current limits of the model can be obtained even in this very early stage.
