Searches for new Physics with Leptons and/or Jets at CMS

Abstract

Using up to 4.98 fb−1 of proton-proton collision data accumulated at a center-of-mass energy of 7TeV in 2011, CMS has searched for signs of new physics in final states with leptons and jets. Many different production and decay signatures have been investigated, showing good agreement with Standard Model predictions. Mass limits for the production of new, heavy particles have been set ranging from few hundred GeV up to several TeV, including limits on the mass of the Z′ andW ′ of the Sequential Standard Model ofM(Z′) > 2.3TeV and M(W ′) > 2.5TeV at 95% confidence level.
