We present a measurement of the differential cross section d sigma/d Sigma E(T)(jet) for the production of multijet events in p (p) over bar collisions where the sum is over all jets with transverse energy E(T)(jet) > E(T)(mm). The measured cross section for events with Sigma E(T)(jet) > 320 GeV is compared to O(alpha(s)(3)) perturbative QCD predictions and QCD parton shower Monte Carlo preidctions. The agreement between the O(alpha(v)(3)) predicted and observed event rates is reasonable for E(T)(min) = 100 GeV, but poorer E(T)(mm) = 20 GeV.

Abstract
We present a measurement of the differential cross section d sigma/d Sigma E(T)(jet) for the production of multijet events in p (p) over bar collisions where the sum is over all jets with transverse energy E(T)(jet) > E(T)(mm). The measured cross section for events with Sigma E(T)(jet) > 320 GeV is compared to O(alpha(s)(3)) perturbative QCD predictions and QCD parton shower Monte Carlo preidctions. The agreement between the O(alpha(v)(3)) predicted and observed event rates is reasonable for E(T)(min) = 100 GeV, but poorer E(T)(mm) = 20 GeV.
