The production and event topology of three-jet events produced in p¯p collisions at √s=1.8 TeV have been studied with the Collider Detector Fermilab Tevatron Collider. distributions angular variables (ψ∗ cosθ∗) describing energy sharing between jets (x3 x4) are found to agree well tree-level QCD calculations. These predicted different shapes for initial-state subprocesses (quark-antiquark, quark-gluon, gluon-gluon). data consistent small expected contribution from quark-antiquark initial...
