Three-jet event,evidence of gluons,in the ZEUS detector at DESY,the German particle physics lab in Hamburg. An electron & proton,accelerated in DESY's HERA collider,enter unseen from left & right. Their collision leads to four clusters of energy deposits (coloured blocks). Three have particle tracks leading back to the interaction point; they are due to jets of particles created by a quark,an antiquark & a gluon produced in the collision. The fourth cluster of energy is due to particles originating from the proton; they leave no tracks because they remain initially within the beam pipe. The gluon,a gauge boson,is the carrier particle of the strong nuclear force | |
