Prize motivation: "for their decisive contributions to the large project, which led to the discovery of the field particles W and Z, communicators of weak interaction"
Field: experimental particle physics
Prize share: 1/2
According to modern physics, four fundamental forces are at work in nature. Weak interaction, which, for example, causes "beta decay" in atomic nuclei, is one of these. In theory, these forces are conveyed by particles - the weak interaction by "W" and "Z" particles. Carlo Rubbia proposed and led experiments that, by allowing protons and antiprotons to collide at very high speeds, would prove the existence of these particles. In this way, the existence of "W" and "Z" particles was verified in 1983.
