A measurement of the two-jet differential cross section, d3σ/dETdη1dη2, based on an integrated luminosity of 86pb−1. The differential cross section is measured as a function of the transverse energy, E⊥, of a jet in the pseudorapidity region 0.1<|η1|<0.7 for four different pseudorapidity bins of a second jet restricted to 0.1<|η2|<3.0.
