The Z boson is a fundamental particle in the Standard Model of particle physics. It is a neutral gauge boson that mediates the weak nuclear force, which is responsible for processes like beta decay in atomic nuclei. The Z boson is produced in high-energy particle collisions and has a short lifespan, decaying into other particles almost immediately. Discovered in 1973 at the CERN laboratory, the Z boson plays a crucial role in understanding the interactions between particles. It is one of the key components of the electroweak theory, which unifies the electromagnetic force and the weak force. Its existence confirmed predictions made by physicists like Sheldon Glashow, Abdus Salam, and Steven Weinberg.
