Inclusive jet cross section in<i>p</i>¯<i>p</i>collisions at √<i>s</i>=1.8 TeV

Abstract

We present a measurement of the inclusive jet cross section in p\ifmmode\bar\else\textasciimacron\fi{}p collisions at \ensuremath{\surd}s =1.8 TeV at the Fermilab Tevatron using the Collider Detector at Fermilab. Good agreement is seen with the predictions of recent next-to-leading-order [O(${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}^{3}$)] QCD predictions. The dependence of the cross section on clustering cone size is reported for the first time. An improved limit on ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}$, a term characterizing possible quark substructure, is set at 1.4 TeV (95% C.L.).
