The CD± and D0 measurements use a cone algorithm oF radius 0.7 For all results shown except For the CD± measurements at 1.96 TeV which also use k T with a D parameter oF 0.7 and midpoint algorithms. The cone/ k T results should be similar iF R cone = D . UA1 (UA2) uses a non-iterative cone algorithm with a radius oF 1.0 (1.3). Recent NLO QCD predictions (such as CTEQ6M) provide a good description oF the CD± and D0 jet cross sections, Rept. on Prog. in Phys. 70 , 89 (2007). Comparisons with the older cross sections are more difficult due to the nature oF the jet algorithms used. CDF :Ph y s . Rev. D75 , 092006 (2007), Phys. Rev. D64 , 032001 (2001), Phys. Rev.

The errors are either statistical only (CD±, D0 (1.96 TeV), UA1, UA2, UA6) or uncorrelated (D0 1.8 TeV, 630 GeV). The data are generally in good agreement with NLO QCD predictions, albeit with a tendency For the data to be above (below) the theory For lower (large) transverse momenta, Phys. Rev.
