Measurement of the inclusive jet cross section at the Fermilab Tevatron p(p)over-bar collider using a cone-based jet algorithm

We present a measurement of the inclusive jet cross section in p (p) over bar collisions at root s = 1.96 TeV based on data collected by the CDF II detector with an integrated luminosity of 1.13 fb(-1). The measurement was made using the cone-based midpoint jet clustering algorithm in the rapidity region of vertical bar y vertical bar < 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.
