Studies of Topological Distributions of the Three- and Four-Jet Events in $\pp$ Collisions at $\sqrt{s}=1800$ GeV with the DØDetector

Abstract

The global topologies of inclusive three-- and four--jet events produced in $\pp$ interactions are described. The three-- and four--jet events are selected from data recorded by the DØdetector at the Tevatron Collider operating at a center--of--mass energy of $\sqrt{s}=1800$ GeV. The measured, normalized distributions of various topological variables are compared with parton--level predictions of tree--level QCD calculations. The parton--level QCD calculations are found to be in good agreement with the data. The studies also show that the topological distributions of the different subprocesses involving different numbers of quarks are very similar and reproduce the measured distributions well. The parton shower Monte Carlo generators provide a less satisfactory description of the topologies of the three-- and four--jet events.
