Title: Measurement of the Differential Cross Section for Events with Large Total Transverse Energy in {ital p}{ovr {ital p}} Collisions at {radical}({ital s}) = 1.8 TeV

Measurement of the Differential Cross Section for Events with Large Total Transverse Energy in {ital p}{ovr {ital p}} Collisions at {radical}({ital s}) = 1.8 TeV We present a measurement of the differential cross section d{sigma}/d{summation}E{sup jet}{sub T} for the production of multijet events in p{ovr p} collisions where the sum is over all jets with transverse energy E{sup jet}{sub T}{gt}E{sup min}{sub T} . The measured cross section for events with {summation}E{sup jet}{sub T}{gt} 320 GeV is compared to O({alpha}{sup 3}{sub s}) perturbative QCD predictions and QCD parton shower Monte Carlo predictions. The agreement between the O({alpha}{sup 3}{sub s}) predicted and observed event rates is reasonable for E{sup min}{sub T}=100 GeV , but poorer for E{sup min}{sub T}=20 GeV . {copyright} {ital 1998} {ital The American Physical Society}
