Abstract

The particle flow distributions in the event plane of 3-jet {Mathematical expression} and of radiative 2-jet {Mathematical expression} events are compared at a centre of mass energy of 35 GeV. The number of particles in the angular region opposite to the gluon in {Mathematical expression} events is found to be significantly reduced relative to the number of particles in the region opposite to the hard photon in {Mathematical expression} events. This depletion is expected from the "string effect" observed in 3-jet events. It can be explained within the framework of QCD as arising from soft gluon interference.
