Two-jet decay of Z particle. Electronic display of an electron-positron collision in the ALEPH detector at CERN,the European particle physics lab near Geneva. The display shows a cross-section of the detector,with the beam tube in the centre (blue) surrounded by various detector components (blue & red). The electron & positron,accelerated to high energy in CERN's LEP collider,annihilate at centre to create a neutral Z particle (one of the carriers of the weak nuclear force). The Z is too short-lived to be detected directly,but reveals itself when it decays into an unseen quark & antiquark which immediately create two back-to- back jets of particles,mainly hadrons | |
