The Two-Jet Differential Cross Section at ${\cal O}(α_s^3)$ in Hadron Collisions

We study the two-jet inclusive cross section via the triply differential distribution $d^3\sigma/dE_{T}d\eta_1 d\eta_2$ to next-to-leading order in QCD. The predicted distributions can be compared directly with forthcoming data from the D0 and CDF experiments at Fermilab. We discuss differences with the leading-order predictions, and examine uncertainties due to the choice of scale and parton density.
