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.
