Three-jet event in the L3 detector at CERN,the European particle physics laboratory outside Geneva. An electron and positron,accelerated to high-energy in CERN's LEP collider,annihilate at the centre of the cylindrical detector (shown in red). Their energy rematerialises as a neutral Z particle. The Z immediately decays into a quark and an antiquark,one of which radiates a gluon,the carrier particle of the strong nuclear force. The quark,antiquark,and gluon instantly give rise to the three jets of particles that spray out through the detector | |
