Abstract
A measurement is presented of the two-jet differential cross section d 3 σ/dE T dη 1 dη 2 at center of mass energy √s=1800 GeV in pp collisions. The results are based on an integrated luminosity of 86 pb -1 collected during 1994 to 1995 by the CDF Collaboration at the Fermilab Tevatron collider. The differential cross section is measured as a function of the transverse energy E T of a jet in the pseudorapidity region 0.1<ǀη 1 ǀ <0.7 for four different pseudorapidity bins of a second jet restricted to 0.1<ǀη 2 ǀ <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 ex, amined in this analysis provides a good description of the data.
