Description:

The thesis presents the results from two searches using dileptons and jets based on 4.98 fb-1 of data taken by the CMS experiment at the Large Hadron Collider during the 2011 run. The first is part of a larger, complete search for supersymmetry using the signal of one isolated lepton, jets and missing transverse energy. Although the search concentrates on a single lepton topology, this thesis outlines the procedure to predict the contribution from dilepton events which, through various processes, feed down into the single lepton control sample. The second is a search for massive, exotic, colored fermions decaying to two jets and a lepton by looking for a peak in the lepton plus two jet invariant mass spectrum. A data-driven method has been developed in order to make a background prediction. The observations are consistent with the standard model background prediction. The results are presented as limits on the cross section of such exotic fermions as a function of mass.
