The Inclusive Jet Cross Section in ppbar Collisions at sqrt{s}=1.8 TeV using the kT Algorithm

We present a preliminary measurement of the central inclusive jet cross section using a successive combination algorithm based on relative transverse momenta ( k ⊥ ) for jet reconstruction. We analyze a 87 . 3 pb − 1 data sample collected by the DØ detector at the Fermilab Tevatron pp Collider during 1994-1995. The cross section, reported as a function of transverse momentum ( p T > 60 GeV) in the central region of pseudo-rapidity ( | η | < 0 . 5), is in reasonable agreement with next-to-leading order QCD predictions. This is the first jet production measurement in a hadron collider using a successive combination type of jet algorithm.
