# Energy fractions of three-jet events in proton-antiproton collisions at sqrt.s = 1.8 TeV

#### Abstract

The leading-order calculation of Quantum Chromodynamics (QCD) for the production of three-parton final states was tested by investigating three-jet events at the Fermilab Tevatron at $\sqrt{s}$ = 1.8 TeV. The integrated luminosity used for this study was 3.9 pb$\sp{-1}$. The three jets were Lorentz boosted to their center-of-mass (COM) frame, and the fraction of the total COM energy each jet carried was calculated. There were 4826 events after cuts were made to eliminate detector bias. The distributions of the energy fractions were found to be inconsistent with a three-body phase space decay model and consistent with QCD.
