Inclusive jet cross section differential in pT
Experiment: CDF (Tevatron Run 2)
Inspire ID: 699933
Status: VALIDATED
Authors:
  • Frank Siegert
References: Beams: p- p+
Beam energies: (980.0, 980.0) GeV
Run details:
  • $p\bar{p}$ -> jets at 1960 GeV

Measurement of the inclusive jet cross section in ppbar interactions at $\sqrt{s}=1.96$ TeV using 385 $\mathrm{pb}^{-1}$ of data. The data cover the jet transverse momentum range from 61 to 620 GeV/c in $0.1 < |y| < 0.7$. This analysis has been updated with more data in more rapidity bins in CDF_2008_S7828950.
