T. Affolder et al., Measurement of the two-jet differential cross section in p(p)over-bar collisions at root s=1800 GeV - art. no. 012001, PHYS REV D, 6401(1), 2001, pp. 2001
A measurement is presented of the two-jet differential cross section d(3)si
gma /dE(T)d eta (1)d eta (2) at center of mass energy roots = 1800 GeV in p
(p) over bar 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 regi
on 0.1<\ <eta>(1)\<0.7 for four different pseudorapidity bins of a second j
et restricted to 0.1<\ eta (2) \<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.
