Studies of Jets and MET at CMS

During the LHC early commissioning phase, CMS recorded about 350k and 20k minimum bias events from proton-proton collisions at $\sqrt{s}$ = 900 GeV and $\sqrt{s}$ = 2360 GeV respectively. Three types of jets and missing transverse energy are reconstructed: from calorimeter energy depositions, from combined calorimeter and tracker information, and from particle flow candidates. We present the properties of inclusive jets and dijet events, as well as missing transverse energy from inclusive events. The collision data are in good agreement with predictions from PYTHIA minimum bias events simulated with the full CMS detector simulation.
