W particles in OPAL detector,CERN
Production & decay of two W particles in the OPAL detector at CERN,the particle physics laboratory near Geneva. The computer display shows OPAL in cross-section (green). An electron & positron,accelerated in CERN's LEP collider,annihilate at centre to produce two W particles. They live too briefly to be seen but reveal themselves by their decays. One W turns into a quark & antiquark which then produce two jets of particles (pale & dark blue tracks leading to yellow & magenta blocks). The other W decays to a muon (orange track,magenta block,red arrow) and an unseen muon- neutrino. The positive & negative W particles are carriers of the weak nuclear force
