Abstract
We present preliminary results of measurements of charged particle jet properties in proton-proton collisions at = 7 TeV using the ALICE detector. Jets are reconstructed using anti - kT, kT and SISCone jet finding algorithms with resolution parameter R = 0.4 in the range of transverse momentum from 20 to 100 GeV/c in the midrapidity region (|η| < 0.5). The uncorrected charged jet spectra obtained using the three different jet finders show good agreement. The data are compared to predictions from PYTHIA-Perugia0, PYTHIA-Perugia2011, and PHOJET. The mean charged particle multiplicity in leading jets increases with increasing jet pT and is consistent with model predictions. The radial distributions of transverse momentum about the jet direction and the distributions of the average radius containing 80% of the total jet pT found in the jet cone (R = 0.4 in this analysis), indicate that high pT jets are more collimated than low pT jets.
