Jet reconstruction in CMS using charged tracks only

We present results on the performance of jet reconstruction in CMS, using charged tracks only. Jet reconstruction with tracks is completely independent from jet finding with calorimeter towers and is an extremely clean and efficient way to find jets, and determine their directions with good precision. A commissioning analysis using approximately 100 μb−1 of minimum bias pp collision data at √S = 7 TeV shows that for jets with pT > 10 GeV/c the agreement between the data and PYTHIA predictions for properties of minimum bias events appears to be good, and there is consistency of track jets and calorimeter-based jets.
