W particle decay in Ua1 detector at CERN
W particle decay. Computer graphic display of an event from the UA1 detector at CERN, the European particle physics laboratory outside Geneva, show- ing the decay of a W particle into an electron (blue track) & a neutrino (reconstructed blue track going upwards & ending in arrow), with other particle tracks in yellow & red. The W, which lives too briefly to be visible, was created in a high-energy proton-antiproton collision in CERNs Super-Proton-Synchrotron collider. A gauge boson & one of the carriers of the weak force, the Ws 1983 discovery at CERN helped confirm the " electr- oweak" theory unifying the electromagnetic & weak forces. The UA1 detector is outlined in red. (Run 6069, Event 228)

EDITORS COMMENTS
This print showcases the intricate decay of a W particle within the UA1 detector at CERN, Europe's renowned particle physics laboratory. Created through a high-energy collision between protons and antiprotons in CERN's Super-Proton-Synchrotron collider, this elusive W particle is too short-lived to be directly observed. However, its presence is vividly depicted through computer graphics. In this visually striking display, we witness the transformation of the W particle into an electron (represented by a distinct blue track) and a neutrino (reconstructed as a blue track ascending towards an arrow). Surrounding these primary tracks are other particles captured in yellow and red hues, adding depth to this mesmerizing scene. The discovery of the W particle at CERN in 1983 played a pivotal role in confirming the "electroweak" theory that unifies two fundamental forces: electromagnetism and weak nuclear force. This groundbreaking finding revolutionized our understanding of subatomic interactions. Outlined prominently in red is the UA1 detector itself, which served as an essential tool for capturing such momentous events. Its sophisticated design allowed scientists to unravel mysteries hidden within particles' behavior and properties. Through this remarkable photograph from Science Photo Library, we catch a glimpse into the extraordinary world of particle physics research conducted at CERN—where cutting-edge technology meets profound scientific exploration.
