Comparison of jet production in<i>p</i>¯<i>p</i>collisions at √<i>s</i>=546 and 1800 GeV

Abstract

Inclusive jet cross sections have been measured in p\ifmmode\bar\else\textasciimacron\fi{}p collisions at \ensuremath{\surd}s =546 and 1800 GeV, using the Collider Detector at Fermilab. The ratio of jet cross sections is compared to predictions from simple scaling and O(${\mathit{a}}_{\mathit{s}}^{3}$) QCD. Our data exclude scaling and lie (1.5--2.4)\ensuremath{\sigma} below a range of QCD predictions.
