Measurement of the differential cross section for events with large total transverse energy in pp Collisions at √ s = 1.8 TeV

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