Measurement of the Two-Jet Differential Cross Section in proton-antiproton Collisions at sqrts = 1800 GeV
CDF Collaboration
Abstract
A measurement is presented of the two-jet differential cross section, d3σ/dET dη1 dη2, at center of mass energy sqrts = 1800 GeV in proton-antiproton collisions. The results are based on an integrated luminosity of 86 pb-1 collected during 1994-1995 by the CDF collaboration at the Fermilab Tevatron collider. The differential cross section is measured as a function of the transverse energy, ET, of a jet in the pseudorapidity region 0.1 < |eta1| < 0.7 for four different pseudorapidity bins of a second jet restricted to 0.1 < |η2| < 3.0. The results are compared with next-to-leading order QCD calculations determined using the CTEQ4 and MRST sets of parton distribution functions. None of the sets examined in this analysis provides a good description of the data.
