Commissioning of TrackJets in pp Collisions at 7 TeV

We present results of jet reconstruction with charged tracks using approximately 100~$\mu$b$^{-1}$ of minimum bias pp collision data at $\sqrt{s}=7~{\rm TeV}$. For jets with $\pt>10~\GeVc$ the agreement between the data and \PYTHIA predictions for properties of inclusive jets and di-jet events appears to be good, as well as the consistency of track-based jets with jets using calorimeter energy depositions. We estimate the effects of several systematic uncertainties, and, using events with more than one reconstructed primary vertex, show that track-based jets measurements are robust in the presence of multiple collisions.
