    Abstract

    We compare the particle flow in the event plane of three-jet qqg (quark-antiquark-gluon) events with the particle flow in radiative annihilation events qq (quark-antiquark-photon) for similar kinematic configurations. In the angular region between quark and antiquark jet, we find a significant decrease in particle density for qqg as compared to qq. This effect is predicted in QCD as a result of destructive interference between soft-gluon radiation from quark, antiquark, and hard gluon.
