Topology of three-jet events in p-barp collisions at sqrt s =1.8 TeV.
Additional Document Info
The production and event topology of three-jet events produced in pp collisions at s=1.8 TeV have been studied with the Collider Detector at Fermilab at the Tevatron Collider. The distributions of the three-jet angular variables (* and cos*) and of the variables describing the energy sharing between jets (x3 and x4) are found to agree well with tree-level QCD calculations. These distributions are predicted to have different shapes for different initial-state subprocesses (quark-antiquark, quark-gluon, and gluon-gluon). The data are consistent with the small expected contribution from quark-antiquark initial states, in agreement with theoretical expectations. 1992 The American Physical Society.
