Measurement of the inclusive jet cross section at the Fermilab Tevatronpp¯collider using a cone-based jet algorithm

We present a measurement of the inclusive jet cross section in $p\overline{p}$ collisions at $\sqrt{s}=1.96\mathrm{TeV}$ based on data collected by the CDF II detector with an integrated luminosity of $1.13{\mathrm{fb}}^{-1}$. The measurement was made using the cone-based midpoint jet clustering algorithm in the rapidity region of $|y|<2.1$. The results are consistent with next-to-leading-order perturbative QCD predictions based on recent parton distribution functions (PDFs), and are expected to provide increased precision in PDFs at high parton momentum fraction $x$. The results are also compared to the recent inclusive jet cross section measurement using the $k_T$ jet clustering algorithm, and we find that the ratio of the cross sections measured with the two algorithms is in agreement with theoretical expectations over a large range of jet transverse momentum and rapidity.
