Abstract (data abstract)
CERN-LHC. The differential charged jet cross sections, jet fragmentation distributions, and jet shapes, such as jet charged particle multiplicity, average radius containing 80% of the reconstructed jet $p_{\rm T}$, and radial transverse momentum distributions, are measured in minimum bias proton-proton collisions at centre-of-mass energy $\sqrt{s}=$ 7 TeV. Jets are reconstructed from charged particle momenta in the mid-rapidity region using the sequential recombination $k_{\rm T}$ and anti-$k_{\rm T}$ as well as the SISCone jet finding algorithms with several resolution parameters in the range $R$ = 0.2 -- 0.6. Differential jet production cross sections are measured with the three jet finders in the transverse momentum interval 20 $< p_{\rm T}^{\rm jet,ch} <$ 100 GeV/$c$ while jet fragmentation and jet shapes are reported for jets in the $p_{\rm T}$ range 20 -- 80 GeV/$c$. Results are presented in comparison to event generators (PYTHIA, HERWIG, PHOJET), for both, without subtraction of underlying events (UE) and after UE subtraction.
