Book excerpt: This thesis presents results for a search for new physics based on 36 pb-1 of data taken during 2010 by the CMS experiment at the Large Hadron Collider (LHC). We specifically look at the signature with a single isolated lepton, jets, and large missing transverse momentum. To predict the standard model backgrounds in this search, two separate and complementary methods are employed, each of which use control samples in the data. The standard model background predictions are consistent with the observed number of events in both the muon and electron channels and for both background prediction methods. In addition, the observed missing transverse momentum distribution agrees well with the standard model prediction. In the absence of a signal we proceed to set limits in the contrained minimal supersymmetric extension of the standard model (CMSSM) parameter space.
